text: We present a photon- and metal-free approach for the radical fluorination
of aliphatic oxalate-activated alcohols. The method relies on the spontaneous
generation of the N-(chloromethyl)triethylenediamine radical dication, a potent
single electron oxidant, from Selectfluor and 4-(dimethylamino)pyridine. The protocol
is easily scalable and provides the desired fluorinated products within only a
few minutes reaction time.

text: We report the visible light photocatalytic cleavage of trityl thioethers or
ethers under pH-neutral conditions. The method results in the formation of the
respective symmetrical disulfides and alcohols in moderate to excellent yield.
The protocol only requires the addition of a suitable photocatalyst and light
rendering it orthogonal to several functionalities, including acid labile protective
groups. The same conditions can be used to directly convert trityl-protected thiols
into unsymmetrical disulfides or selenosulfides, and to cleave trityl resins in
solid phase organic synthesis.

text: The multicomponent approach allows to incorporate several functionalities
into a single covalent organic framework (COF) and consequently allows the construction
of bifunctional materials for cooperative catalysis. The well-defined structure
of such multicomponent COFs is furthermore ideally suited for structure-activity
relationship studies. We report a series of multicomponent COFs that contain acridine-
and 2,2’-bipyridine linkers connected through 1,3,5-benzenetrialdehyde derivatives.
The acridine motif is responsible for broad light absorption, while the bipyridine
unit enables complexation of nickel catalysts. These features enable the usage
of the framework materials as catalysts for light-mediated carbon−heteroatom cross-couplings.
Variation of the node units shows that the catalytic activity correlates to the
keto-enamine tautomer isomerism. This allows switching between high charge-carrier
mobility and persistent, localized charge-separated species depending on the nodes,
a tool to tailor the materials for specific reactions. Moreover, nickel-loaded
COFs are recyclable and catalyze cross-couplings even using red light irradiation.

text: Visible-light photocatalysis provides numerous useful methodologies for synthetic
organic chemistry. However, the mechanisms of these reactions are often not fully
understood. Common mechanistic experiments mainly aim to characterize excited
state properties of photocatalysts and their interaction with other species. Recently,
in situ reaction monitoring using dedicated techniques was shown to be well-suited
for the identification of intermediates and to obtain kinetic insights, thereby
providing more holistic pictures of the reactions of interest. This minireview
surveys these technologies and discusses selected examples where reaction monitoring
was used to elucidate the mechanism of photocatalytic reactions.

text: The influence of structural modifications on the catalytic activity of carbon
materials is poorly understood. A collection of carbonaceous materials with different
pore networks and high nitrogen content was characterized and used to catalyze
four reactions to deduce structure–activity relationships. The CO2 cycloaddition
and Knoevenagel reaction depend on Lewis basic sites (electron-rich nitrogen species).
The absence of large conjugated carbon domains resulting from the introduction
of large amounts of nitrogen in the carbon network is responsible for poor redox
activity, as observed through the catalytic reduction of nitrobenzene with hydrazine
and the catalytic oxidation of 3,3′,5,5′-tetramethylbenzidine using hydroperoxide.
The material with the highest activity towards Lewis acid catalysis (in the hydrolysis
of (dimethoxymethyl)benzene to benzaldehyde) is the most effective for small molecule
activation and presents the highest concentration of electron-poor nitrogen species.

text: Covalent organic frameworks (COFs) are structurally tuneable, porous and crystalline
polymers constructed through the covalent attachment of small organic building
blocks as elementary units. Using the myriad of such building blocks, a broad
spectrum of functionalities has been applied for COF syntheses for broad applications,
including heterogeneous catalysis. Herein, we report the synthesis of a new family
of porous and crystalline COFs using a novel acridine linker and benzene-1,3,5-tricarbaldehyde
derivatives bearing a variable number of hydroxy groups. With the broad absorption
in the visible light region, the COFs were applied as photocatalysts in metallaphotocatalytic
C−N cross-coupling. The fully β-ketoenamine linked COF showed the highest activity,
due to the increased charge separation upon irradiation. The COF showed good to
excellent yields for several aryl bromides, good recyclability and even catalyzed
the organic transformation in presence of green light as energy source.

text: We present a divergent strategy for the fluorination of phenylacetic acid
derivatives that is induced by a charge-transfer complex between Selectfluor and
4-(dimethylamino)pyridine. A comprehensive investigation of the conditions revealed
a critical role of the solvent on the reaction outcome. In the presence of water,
decarboxylative fluorination through a single-electron oxidation is dominant.
Non-aqueous conditions result in the clean formation of α-fluoro-α-arylcarboxylic
acids.

text: Photoredox-mediated Ni-catalyzed cross-couplings are powerful transformations
to form carbon–heteroatom bonds and are generally photocatalyzed by noble metal
complexes. Low-cost and easy-to-prepare carbon dots (CDs) are attractive quasi-homogeneous
photocatalyst alternatives, but their applicability is limited by their short
photoluminescence (PL) lifetimes. By tuning the surface and PL properties of CDs,
we designed colloidal CD nano-photocatalysts for a broad range of Ni-mediated
cross-couplings between aryl halides and nucleophiles. In particular, a CD decorated
with amino groups permitted coupling to a wide range of aryl halides and thiols
under mild, base-free conditions. Mechanistic studies suggested dynamic quenching
of the CD excited state by the Ni co-catalyst and identified that pyridinium iodide
(pyHI), a previously used additive in metallaphotocatalyzed cross-couplings, can
also act as a photocatalyst in such transformations.

text: We demonstrate that several visible-light-mediated carbon−heteroatom cross-coupling
reactions can be carried out using a photoactive NiII precatalyst that forms in
situ from a nickel salt and a bipyridine ligand decorated with two carbazole groups
(Ni(Czbpy)Cl2). The activation of this precatalyst towards cross-coupling reactions
follows a hitherto undisclosed mechanism that is different from previously reported
light-responsive nickel complexes that undergo metal-to-ligand charge transfer.
Theoretical and spectroscopic investigations revealed that irradiation of Ni(Czbpy)Cl2
with visible light causes an initial intraligand charge transfer event that triggers
productive catalysis. Ligand polymerization affords a porous, recyclable organic
polymer for heterogeneous nickel catalysis of cross-coupling reactions. The heterogeneous
catalyst shows stable performance in a packed-bed flow reactor during a week of
continuous operation.

text: Controlling the selectivity of a chemical reaction with external stimuli is
common in thermal processes, but rare in visible-light photocatalysis. Here we
show that the redox potential of a carbon nitride photocatalyst (CN-OA-m) can
be tuned by changing the irradiation wavelength to generate electron holes with
different oxidation potentials. This tuning was the key to realizing photo-chemo-enzymatic
cascades that give either the (S)- or the (R)-enantiomer of phenylethanol. In
combination with an unspecific peroxygenase from Agrocybe aegerita, green light
irradiation of CN-OA-m led to the enantioselective hydroxylation of ethylbenzene
to (R)-1-phenylethanol (99 % ee). In contrast, blue light irradiation triggered
the photocatalytic oxidation of ethylbenzene to acetophenone, which in turn was
enantioselectively reduced with an alcohol dehydrogenase from Rhodococcus ruber
to form (S)-1-phenylethanol (93 % ee).

text: Metallaphotocatalytic cross-coupling reactions are typically carried out by
combining homogeneous or heterogeneous photocatalysts with a soluble nickel complex.
Previous attempts to realize recyclable catalytic systems use immobilized iridium
complexes to harvest light. We present bifunctional materials based on semiconductors
for metallaphotocatalytic C−S cross-coupling reactions that can be reused without
losing their catalytic activity. Key to the success is the permanent immobilization
of a nickel complex on the surface of a heterogeneous semiconductor through phosphonic
acid anchors. The optimized catalyst harvests a broad range of the visible light
spectrum and requires a nickel loading of only ∼0.1 mol %.

text: Carbon dots have been previosly immobilized on titanium dioxide to generate
photocatalysts for pollutant degradation and water splitting. Here we demonstrate
that these nanocomposites are valuable photocatalysts for metallaphotocatalytic
carbon–heteroatom cross-couplings. These sustainable materials show a large applicability,
high photostability, excellent reusability, and broadly absorb across the visible-light

text: Visible light photocatalysis has become a powerful tool in organic synthesis
that uses photons as traceless, sustainable reagents. Most of the activities in
the field focus on the development of new reactions via common photoredox cycles,
but recently a number of exciting new concepts and strategies entered less charted
territories. We survey approaches that enable the use of longer wavelengths and
show that the wavelength and intensity of photons are import parameters that enable
tuning of the reactivity of a photocatalyst to control or change the selectivity
of chemical reactions. In addition, we discuss recent efforts to substitute strong
reductants, such as elemental lithium and sodium, by light and technological advances
in the field.

text: The cleavage of benzyl ethers by catalytic hydrogenolysis or Birch reduction
suffers from poor functional group compatibility and limits their use as a protecting
group. The visible-light-mediated debenzylation disclosed here renders benzyl
ethers temporary protective groups, enabling new orthogonal protection strategies.
Using 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) as a stoichiometric or catalytic
photooxidant, benzyl ethers can be cleaved in the presence of azides, alkenes,
and alkynes. The reaction time can be reduced from hours to minutes in continuous
flow.

text: Metallaphotocatalysis typically requires a photocatalyst to harness the energy
of visible-light and transfer it to a transition metal catalyst to trigger chemical
reactions. The most prominent example is the merger of photo- and nickel catalysis
that unlocked various cross-couplings. However, the high reactivity of excited
photocatalyst can lead to unwanted side reactions thus limiting this approach.
Here we show that a bipyridine ligand that is subtly decorated with two carbazole
groups forms a nickel complex that absorbs visible-light and promotes several
carbon–heteroatom cross-couplings in the absence of an exogenous photocatalysts.
The ligand can be polymerized in a simple one-step procedure to afford a porous
organic polymer that can be used for heterogeneous nickel catalysis in the same
reactions. The material can be easily recovered and reused multiple times maintaining
high catalytic activity and selectivity.

text: Controlling the selectivity of a chemical reaction with external stimuli is
common in thermal processes, but rare in visible-light photocatalysis. Here we
show that the redox potential of a carbon nitride photocatalyst (CN-OA-m) can
be tuned by changing the irradiation wavelength to generate electron holes with
different oxidation potentials. This tuning was the key to realizing photo-chemo-enzymatic
cascades that give either the (S)- or the (R)-enantiomer of phenylethanol. In
combination with an unspecific peroxygenase from Agrocybe aegerita, green light
irradiation of CN-OA-m led to the enantioselective hydroxylation of ethylbenzene
to (R)-1-phenylethanol (99% ee). In contrast, blue light irradiation triggered
the photocatalytic oxidation of ethylbenzene to acetophenone, which in turn was
enantioselectively reduced with an alcohol dehydrogenase from Rhodococcus ruber
to form (S)-1-phenylethanol (93% ee).

text: The combination of nickel and photocatalysis has unlocked a variety of cross-couplings.
These protocols rely on a few photocatalysts that can only convert a small portion
of visible light (<500 nm) into chemical energy. The high-energy photons that
excite the photocatalyst can result in unwanted side reactions. Dyes that absorb
a much broader spectrum of light are not applicable because of their short-lived
singlet excited states. Here, we describe a self-assembling catalyst system that
overcomes this limitation. Immobilization of a nickel catalyst on dye-sensitized
titanium dioxide results in a material that catalyzes carbon–heteroatom and carbon–carbon
bond formations. The modular approach of dye-sensitized metallaphotocatalysts
accesses the entire visible light spectrum and allows tackling selectivity issues
resulting from low wavelengths strategically. The concept overcomes current limitations
of metallaphotocatalysis by unlocking the potential of dyes that were previously
unsuitable.
