(Matrix presented) This report details the kinetic responses of nine compounds of type 6 to ring-closing metathesis as promoted by 2 to give the identical product 7. The experimental observations have been subjected to Hammett analysis. The ρ value for the composite aromatic derivatives (R = p-XC6H4-) differs from that of the aliphatic series, although both are negative because electron-donating groups accelerate the reaction.
