Reaction of the platinum(0) complex [{Pt(LL)}2(μ-LL)] [LL = (ViMe2Si)2O] with PR3 (R = C6H4Me-p or C6H11-c) or PPh2CH2CBut2OH yields, by displacement of the bridging vinylsiloxane ligand, complexes having both a phosphine and a vinylsiloxane as co-ligands. There is evidence for interaction between the platinum atom and the OH moiety in [Pt(LL)(PPh2CH2CBut2OH)]. Reaction of the analogous nickel(0) complex [{Ni(LL)}2(μ-LL)] with a tertiary phosphine yields [Ni(LL)PR3] (R = Ph, C6H11-c or C6H4Me-p). The zinc reduction of [Ni(PPh3)2Cl2] in the presence of (ViPh2Si)2O (PLL) yields the complex [Ni(PLL)PPh3]. X-ray molecular structures of the crystalline complexes [Pt(LL)P(C6H4Me-p)3], [Pt(LL)(PPh2CH2CBut2OH)], [Ni(LL){P(C6H11-c)3}] and [Ni(PLL)(PPh3)] show a trigonal planar metal environment and chair conformation for the M(LL) and M(PLL) units.
