| Abstract: | XPd(μ-dppm)2Pt(C6F5) (X = Cl (I), Br (II)) have been prepared by reacting Pd2(dba)3·CHCl3 and PtX- (C6F5)(η1-dppm)2. Reaction of complex I with SnCl2 gives the SnCl3− derivative, whilst ligands L (PPh3, P(OPh)3, SbPh3) render the cationic complexes. The species R2N+, SO2 or MeOOC)CCCOOMe insert into the PdPt bond of I to give A-frame Pd(II)- Pt(II) complexes. The reactions of CIPd(μ-dppm)2- Pt(C6F5) with isonitriles CNR (R = p-Tol, Cy) lead to products containing either terminal or inserted isocyanide or both. |
