The First Carbene-tethered Polymeric Catalyst

When employed for the RCM of select diene substrates, the yields obtained with supported catalyst (10) matched those acquired with the homogeneous catalyst (9) in all but one case (entry 2, Tab. 11.1). This report places emphasis on the operational simplicity of these metathesis reactions. After suspension of the catalyst resin in a solution of substrate, the mixture was agitated for forty minutes
