Treatment of cis- with ButNC gives tNC)2Pt(μ-dppm)2Pt(CNBut)2>(4+), isolated as the PF6(1-) salt (dppm = Ph2PCH2PPh2).Treatment of Cl2 (M = Pt or Pd) with two equivalents of ButNC or MeNC gave fluxional, mononuclear isonitrile complexes of type (2+), isolated as their PF6(1-) or BPh4(1-) salts.The palladium salts readily lose the CNR ligands.The unidentate-dppm complexes of type (2+) react with AgPF6, HgCl2, or to give heterobimetallic complexes with μ-dppm ligands, but these were not isolated in a pure state.However, the salts Cl2 (M = Pt or Pd) react with the compounds (R = Me, But, or p-tolyl) to give the heterobimetallic complexes (1+) in high yield.These were isolated as Cl(1-), BPh4(1-), or PF6(1-) salts.The salt t)2(dppm-P)2>Cl2, prepared in situ from Cl2 and ButNC, reacts with 4> or to give tNC)ClPt(μ-dppm)2MCl>Cl (M = Ag or Au).Treatment of Cl2 with CPh)(CNBut)> gives tNC)(PhCC)Pt(μ-dppm)2AuCl>Cl.Treatment of tNC)ClPt(μ-dppm)2AgCl>Cl with gives the complex tNC)ClPt(μ-dppm)2RhCl(CO)> and silver chloride in a transmetallation reaction.I.r. and 1H-, 31P-, and 195Pt- n.m.r. data are given and discussed.
