Here, we report the synthesis and characterization of a bipincer nickel complex containing bipyridine-based bisphosphine and its catalytic application in quinoline synthesis and α-alkylation of ketones. The reaction of [2,2′-{C5H3N-3-N(H)C(O)C6H4PPh2-o}2] (1) with [NiCl2(DME)] afforded bipincer complex [{NiCl)(2,2′-C5H3N-3-N(H)C(O)C6H4PPh2-o)}-κ3-P,N,N]2 (2). Complex 2 catalysed efficiently the synthesis of quinoline derivatives via acceptor-less dehydrogenative coupling of 2-aminobenzyl alcohol and ketones or secondary alcohols, and also α-alkylation of ketones with alcohols with a very low catalyst loading (0.5 mol%) at 110 °C.
