P,N-chelates of nickel NiCl[2-(Ph2P)C6H4NR](PMe3) (1: R = H; 2: R = SiMe3) have been obtained from NiCl2(PMe3)2 and 2-(Ph2P)C6H4NRLi. Reaction with MeLi affords methylnickel compounds NiMe[2-(Ph2P)C6H4NR](PMe3) (3: R = H; 4: R = Me; 5: R = SiMe3). By the same route NiMe[2-(R1R2P)C6H4NR](PMe3) (6: R1 = R2 = CHMe2) was synthesized. Solutions in THF contain cis and trans isomers of square-planar complexes
