A chiral iridium complex serves as a sensitizer for photoredox catalysis and at the same time provides very effective asymmetric induction for the enantioselective alkylation of 2-acyl imidazoles; the metal centre simultaneously serves as the exclusive source of chirality, the catalytically active Lewis acid centre, and the photoredox centre.
