XPt(μ-dppm)2Pd(C6F5) (X = Cl (I), Br (II), C6F5 (III) have been prepared by treating PdX(C6F5)(η¹-dppm)2 with Pt(COD)2 or Pt(PPh3)4.Substitution reactions of I yielded neutral (SCN) or cationic (PPh3, py) derivatives.The species R2N⁺, SO2 or (formula) insert into the Pd-Pt bond of I to give A-frame Pd^II-Pt^II complexes, but reaction with SnCl2 gives the SnCl3^- derivative.The reactions of X-Pt(μ-dppm)2Pd(C6F5) X = Cl (I), C6F5 (III) with isonitriles RNC (R = p-Tol, Cy, t-Bu) has been studied; the nature of the products obtained depends on the starting material, the isonitrile, and the reaction conditions.The molecular structure of ClPt(μ-dppm)2Pd(C6F5) has been established by a single crystal X-ray study.
