A visible light driven nickel carbonylation catalyst has been develop. This offers a method for carbonylative coupling reactions with an earth abundant metal at ambient temperature for the conversion of alkyl halides into synthetically versatile acid chlorides. The acid chlorides can then be transformed into an array of challenging ester, thioester and amide products.
