Abstract

The phosphanylthiol PPh(2-C6H4SH)(2) reacts with the Ni-II and Pd-II complexes [MCl2L2] in the presence of NaOEt to give the mononuclear derivatives [M{PPh(C6H4S)(2)}L] [M = Ni, L = PPh3 (1), PPh2Me (2); M = Pd, L = PPh3 (3)]. The analogous reaction starting with complexes containing bidentate ligands [MX2(L-L)] produces different results depending on the ligand used. The complexes [M{PPh(C6H4S)(2)}(dppm)] [M = Ni (4), Pd (5)], with an unligated phosphorus atom in the diphosphdne are obtained with bis(diphenylphosphanyl)methane (dppm), while the dinuclear complexes [M-2(mu-dppe){PPh(C6H4S)(2)}] [M = Ni (6), Pd (7)] are isolated in the case of 1,2-bis(diphenylphosphanyl)ethane (dppe). With 1,10-phendtithroline (phen), the complexes [M{PPh(C6H4S)(2)}(phen)] [M = Ni (8), Pd (9)] are obtained, but when 2,2'-bipyridine is used the dinuclear compounds [M{PPh(C6H4S)(2)}](2) [M = Ni (10), Pd (11)] are isolated instead. Complexes 10 and 11, which Can be obtained starting from NiCl2 or [PdCl2(NCPh)(2)] respectively, afford complexes 1-7 when treated with the respective phosphanes in the appropriate stoichiometries, The structures of 2, 7 and 10 have been confirmed by X-ray analysis.
