An extensive range of functionalized aliphaticketones with good functional-group tolerance has been prepared by a NiI -promoted coupling of either primary or secondary alkyl iodides with NN2 pincer NiII -acyl complexes. The latter were easily accessed from the corresponding NiII -alkyl complexes with stoichiometric CO. This Ni-mediated carbonylative coupling is adaptable to late-stage carbon isotope
