| Abstract: | Reactions of PdRR′(η1-dppm)2 (R = R′= C6F5 or C6Cl5; R = C6F5, R′= Cl; dppm = Ph2PCH2PPh2) with the gold derivatives ClAu(tht), C6F5Au(tht), (C6F5)3Au(tht) or O3ClOAuPPh3 (tht = tetrahydrothiophen) in appropriate ratios yield the bi- or tri-nuclear complexes PdRR′(dppm)2AuCl, PdRR′(dppm)2Au(C6F5); PdRR′(dppm)2Au(C6F5)3; PdRR′(dppmAuCl)2; PdRR′(dppmAuC6F5)2; PdRR′dppmAu(C6F5)3]2, PdRR′(dppm)2Au]X (X = ClO4 or BPh4); PPh3Au(dppm)Pd(C6F5)2(dppm)AuCl]ClO4 or PPh3 Au(dppm)Pd(C6F5)2(dppm)Au(C6F5)3]ClO4. The structure of trans-Pd(C6F5)2dppmAu(C6F5)]2 has been determined by X-ray diffraction. |
