Photochemical regioselective C–H arylation of imidazo[1,2-a]pyridine derivatives using chlorophyll as a biocatalyst and diazonium salts

This communication describes the development of a mild method for the arylation of imidazo[1,2- a ]pyridine with diazonium salt derivatives and using chlorophyll as a biocatalyst via visible-light catalysis.
