isocyanates at the benzylic position upon irradiation with visiblelight in the presence of an iridium photoredox catalyst, a bromide anion, and a nickel catalyst, producing N-substituted α-aryl amides. An analogous carbamoylation reaction of aliphatic C–H bonds of alkanes took place when UV light and a diaryl ketone were used instead of visiblelight and the iridium complex. The present reaction offers
