The synthesis of [Rh,2(COD)2(dppm)(μ2- Cl)]BF4 (1) (COD = 1,5-cyclooctadiene, dppm = bis-(diphenylphosphino) methane) from simple precursors is reported. This is a rare example of a dirhodium complex with an open [Rh2(μ2-dppm) (μ2-Cl)] core. The complex has been used to affect the hydrogenation of styrene and benzo[b]thiophene with total selectivity and competitive rates of reaction. The recycling of the catalyst has been achieved by the entrapment of 1 in silica by a sol-gel method to produce a recyclable solid catalyst.
