Alkylbenzenes coupled with isocyanates at the benzylic position upon irradiation with visible light 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 CH bonds of alkanes took place when UV light and a diaryl ketone were used instead of visible light and the iridium complex. The present reaction offers a straightforward and atom-economical method for the synthesis of carboxamides starting from hydrocarbons with one-carbon extension.
Palladium-catalyzed amidation of N-tosylhydrazones with isocyanides

Aminocarbonylation of N-tosylhydrazones: The direct formation of ketenimines from carbenes and isocyanides is limited to the reaction of Fischer carbene complexes or some specially stabilized carbenes with isocyanides. A Pd-catalyzed amidation of N-tosylhydrazones with isocyanides via a ketenimine intermediate in the presence of water is described. The method offers a general way to synthesize amides from carbonyl compounds through one-carbon extension (see scheme). Copyright
