Treatment of aminobis(methylphosphine) complexes of nickel(II) with carboxylic acids in the presence of silver(I) salts in dichloromethane gives the corresponding nickel(II) complexes of the type [NiA(P-P] where A = CO(3)(-) (carbonate), (2), 2-(-)OC(6)H(4)CO(2)(-) (salicylate, Sal), (3), (-)O(2)CCH(2)CH(2)CH(NH(2))CO(2)(-) (glutamate, Glu), (4), (-)O(2)CCH(2)CH(2)CO(2)(-) (succinicate, Suc), (5); P-P = (Cy(2)PCH(2))(2)NMe (dcpam), (Ph(2)PCH(2))(2)NMe (dppam). The complexes have been characterized by spectroscopic techniques such as (31)P-[(1)H] NMR, FT-IR, UV-Vis, and mass spectrometry.
