The reactivity of the dinuclear halo-bridged cycloplatinated complex [Pt(μ-Cl){(κ2-P,C)P(OC6H4)(OPh)2}]2 towards neutral ligands

The reactivity of ( cis - + trans -)[Pt(μ-Cl){(κ 2 -P,C)P(OC 6 H 4 )(OPh) 2 }] 2 ( 1 ) towards several ligands L (L = RCN, P(OMe) 3 , DMSO, NHEt 2 , py, CO, C 2 H 4 , C 8 H 16 ) has been studied. Ethylene and 1-octene do not react while the other reactions proceed with cleavage of the halide bridge and formation of one or both geometrical isomers of [PtCl{(κ 2 -P,C)P(OC 6 H 4 )(OPh) 2 }L] ( 2 – 8 ) depending on the nature of the entering ligand. In some cases equilibrium reactions (L = RCN, DMSO, CO, py) were observed. The structures of [SP4-3]-[PtCl{(κ 2 -P,C)P(OC 6 H 4 )(OPh) 2 }(S)DMSO] ([SP4-3]- 4 ) and [SP4-4]-[[PtCl{(κ 2 -P,C)P(OC 6 H 4 )(OPh) 2 }py] ([SP4-4]- 6 ) are reported.
