Palladium, dichlorobis catalysis

Another application found for phospholes in catalysis is in the insertion of carbon monoxide into a carbon-halogen bond <86POL9ll>. rrans-Dichlorobis(l,2,5-triphenylphosphole)palladium(II) was effective as a catalyst at atmospheric pressure and was superior to the complex based on triphenylphosphine (Equation (72)).
