Abstract:	Reaction of monophosphinite ligand, 2-(diphenylphosphinoxy)naphthyl, C10H7OPPh2 (1) with elemental sulphur or selenium gives the corresponding sulphide C10H7OP(S)Ph-2 (2) or selenide C10H7OP(Se)Ph-2 (3) derivatives. Reaction of 1 with [CpRu(PPh3)(2)Cl] gives monosubstituted complex, [CpRu(C10H7OPPh2)(PPh3)Cl] (4) as well as the disubstituted complex, [CpRu(C10H7OPPh2)(2)Cl] (5) depending upon the reaction conditions. Treatment of 1 with [Rh(CO)(2)Cl](2) affords a trans-complex, [Rh(CO)(C10H7OPPh1)(2)Cl] (6). Reaction of 1 with [Pd(COD)Cl-2] results in the formation of an unexpected chloro-bridged dipalladium complex; [Pd(PPh2O)(PPh2OH)(mu-Cl)](2) (7), whereas similar reaction with [Pt(COD)Cl-2] gives cis[Pt(C10H7OPPh2)(2)Cl-2] (8) in good yield.
