| Abstract: | Two pincer-type nickel iminophosphinite complexes, (2-(CH NR)-6-(OPR′2)C6H3)NiCl] (R = 2,6-iPr2C6H3, R′ = Ph (2a) or iPr (2b)), were synthesized from the reactions of bis(1,5-cyclooctadiene)nickel(0) and corresponding iminophosphinite ligands. The solid state structures of the nickel pincer complexes were determined by X-ray single crystal diffraction studies. They were successfully employed in the Kumada reaction of non-activated aryl chlorides and phenylmagnesium bromide at room temperature. |
