Abstract
The development of a nickel-mediated aminocarbonylation utilizing NN2 -pincer Ni-complexes, alkylzinc reagents, stoichiometric carbon monoxide and amines is described for the first time, which can be adapted to late-stage carbon-isotope labeling. This work expands the scope of the highly established palladium-promoted version of the reaction, by allowing carbon-sp3 fragments to take part in the three-component reaction. Finally, the results obtained show a remarkable effect of the pincer ligand for the reductive elimination step with the amine, which is followed by 13 C NMR spectroscopy studies.
