P212121. All complexes were utilized as pre-catalysts in a comparative study to probe relevant features of the palladium active species during high temperature Suzuki–Miyaura cross-coupling catalysis. Relatively higher catalytic activities were obtained for complexes bearing the bidentate ligands that possess weaker azole donor arms. Results obtained suggest that ligand dissociation steps may be important

A cobaloxime‐catalyzed acceptorless dehydrogenative cyclization of o‐teraryls was developed. In stark contrast to the established methods such as the Scholl or Mallory reactions, this method does not require any strong acids or oxidants, and shows high atom economy and a broad substrate scope. It operates at near room temperature with light as the source of energy. Acid‐ or oxidant‐sensitive functional
