Resumen

Dinuclear rhodium complexes of the type [Rh2(C2O4)(diolefin)2] (diolefin)2 1,5-cyclooctadiene, 2,5-norbornadiene and tetrafluorobenzobarrelene) with bridging oxalate ligands have been obtained by reaction of [Rh(acac)(diolefin)] with oxalic acid (2: 1 mol ratio). The use of a 1 : 1 molar ratio affords [Rh(HC2O4)(COD)], that reacts with [Ir(acac)(COD)] yielding the heterodinuclear [(COD)Rh(C2O4)Ir(COD)] complex. Treatment of [Rh2(C2O4)(diolefin)2] complexes with phenanthroline type ligands leads to ionic complexes of formula [Rh(diolefin) (phen)][Rh(C2O4)(diolefin)]. Bubbling of carbon monoxide through solutions of the diolefin complexes leads to the formation of carbonylrhodium species of formula [Rh2(C2O4)(CO)2L2] (L = CO, PPh3 t-BuNC) or [Rh(CO)2(phen)] - [Rh(C2O4)(CO)2]. Other related malonate complexes are also described. © 1985.
