By employing a parallel reactor platform for rapid reaction screening and discovery at elevated temperatures, various metal/ligand/base combinations were evaluated for their ability to enable biaryl formation through C-H activation. The combination of cobalt(III) acetylacetonate and lithium bis(trimethylsilyl)amide was subjected to further process intensification at 200 °C (15 bar), allowing a significant reduction of the catalyst/base loading and a dramatic increase in catalytic efficiency (turnover frequency) by a factor of 1000 compared to traditional protocols. The high-throughput screening additionally identified novel nickel- and copper-based metal/ligand combinations that favored an amination pathway competing with C-H activation, with the addition of ligands, such as 1,10-phenanthroline, having a profound influence on the selectivity. In addition to metal-based catalysts, high-T/p process windows were also successfully applied to transition-metal-free systems, utilizing 1,10-phenanthroline as organocatalyst."}],"_id":"11964","author":[{"last_name":"Pieber","id":"93e5e5b2-0da6-11ed-8a41-af589a024726","full_name":"Pieber, Bartholomäus","first_name":"Bartholomäus","orcid":"0000-0001-8689-388X"},{"first_name":"David","full_name":"Cantillo, David","last_name":"Cantillo"},{"first_name":"C.
