(S)-(+)-COP-Cl Catalyst is catalyst for enantioselective allylation of phenols with (E)-allylic alcohols to branched chiral allylic aryl ethers and asymmetric aza-Claisen rearrangement and ring-closing metathesis. It is also employed in the rearrangement of allylic trichloracetimidates to allylic amines of high enantiopurity.
