Abstract

The synthesis of [Rh-2(COD)(2)(dppm)(mu(2)-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 [Rh-2(mu(2)-dppm)(mu(2)-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.
