✦ Synopsis

This work was supported by the Deutsche Forschungsgemeinschaft (SFB 347) and the Fonds der Chemischen Industrie. Scheme 1. Indirect substitution of the SbiPr 3 ligands in 1 by PMe 3 and subsequent reaction to give 4. Scheme 2. Synthesis of the tetranuclear rhodium complexes 5 and 7, which are in equilibrium with the dinuclear complexes 5' and 7'.

Novel dinuclear rhodium complexes of the general composition [Rh2Cl2(mu-CRR')2(mu-SbiPr3)] (4-6) were prepared by thermolysis of the mononuclear precursors trans-[RhCl(=CRR')(SbiPr3)2] in excellent yield. The X-ray crystal structure analysis of 4 (R = R' = Ph) confirms the symmetrical bridging posit
