Di-μ-chlorotetrakis(η2-methylenecyclopropane)dirhodium. A Highly Active Catalyst for Hydrosilylation of Alkenes and Alkynes

Di-μ-chlorotetrakis(η²-methylenecyclopropane)dirhodium, a novel rhodium complex containing the methylenecyclopropane ligand, is a more active catalyst for the hydrosilylation of alkenes and alkynes than either a similar ethylene complex or the Wilkinson catalyst.
