XPt(μ-dppm)2 Pd(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 yield neutral (SCN) or cationic (PPh3, py) derivatives. The species R2N+, SO2 or RC≡CR (R = COOMe) insert into the PdPt bond of I to give A-frame PdII-PtII 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.
