The new nickel isocyanide complex [Ni(tri-phos)(CN-xylyl)] (1) has been prepared by the reaction of Ni(COD)2, triphos (triphos = bis(2-diphenylphosphi-noethyDphenylphosphine), and CN-xylyl (xylyl = 2,6-Me2C6H3). Complex 1 adds 2 equiv of HBF4 to afford a stable dicationic nickel carbene complex, [Ni(triphos)C(H)N(H)xylyl]2+(BF4)2- (2), in high yield. Nickel carbene 2 exhibits transfer hydrogenation of ketones.
