The bench-stable, reusable nano-Fe3O4@Al2O3 catalyst can selectively reduce functionalized nitroarenes at 1 mol % catalyst loading by using a 20 mol % excess of hydrazine hydrate in an elevated temperature regime (150 °C, reaction time 2–6 min in batch). For continuous-flow processing, the catalyst material is packed into dedicated cartridges and used in a commercially available high-temperature/-pressure flow device. In continuous mode, reaction times can be reduced to less than 1 min at 150 °C (30 bar back pressure) in a highly intensified process. The nano-Fe3O4@Al2O3 catalyst demonstrated stable reduction of nitrobenzene (0.5 M in MeOH) for more than 10 h on stream at a productivity of 30 mmol h−1 (0.72 mol per day). Importantly, virtually no leaching of the catalytically active material could be observed by inductively coupled plasma MS monitoring.","lang":"eng"}],"doi":"10.1002/cssc.201402455","author":[{"last_name":"Moghaddam","full_name":"Moghaddam, Mojtaba Mirhosseini","first_name":"Mojtaba Mirhosseini"},{"orcid":"0000-0001-8689-388X","full_name":"Pieber, Bartholomäus","first_name":"Bartholomäus","id":"93e5e5b2-0da6-11ed-8a41-af589a024726","last_name":"Pieber"},{"last_name":"Glasnov","first_name":"Toma","full_name":"Glasnov, Toma"},{"last_name":"Kappe","first_name":"C.
