Green-light Cerium Photocatalysis enabled by Pyridine N-oxide Ligands

Abstract

Pyridine N-oxides are reported as neutral ligands in cerium photocatalysis. By using those neutral ligands, photoactive Ce(IV)-species are generated, which show an extensive bathochromic shift compared to previously employed cerium-based complexes. This allows the effective utilization of green light in the redox-neutral CH-hydrazination of small molecules under very mild photocatalytic conditions
