A remarkable ancillary ligand effect in living ring-opening metathesis polymerisation
Abstract
The microstructure of poly {3,5-[1,2-bis(trifluoromethyl)cyclopentenylene]vinylene}obtained via living ring-opening metathesis polymerisation initiated by Schrock catalysts, [Mo(CHR1)(NAr)(OR2)2], is a sensitive function of the alkoxide ligands.
