摘要:
The mixed-ligand di-mu-chloro-bridged rhodium dimers [(eta(2)-C8H14)(eta(4)-2-methylbuta-1,3-diene)Rh(mu-Cl)](2) and [eta(2)-C8H14)(eta(4)-2,3-dimethylbuta-1,3-diene)Rh(mu-Cl)](2) were synthesized and characterized. These compounds are key precursors in the preparative synthesis of the acyclic (pi-allyl)-closo-rhodacarborane complexes [3- (pi-(R ''-allyl)}-1-R-2-R'-closo-3,1,2-RhC2B9H9], which were obtained earlier via the one-pot metallation of the K+ salts of the [7-R-8-R'-nido-7,8-C2B9H10](-) anions with [(eta(2)-C8H14)(4)Rh-2(mu-Cl)(2)] in the presence of substituted buta-1,3-diene ligands.
