Abstract

We report here the mechanism-based design of a ring-opening metathesis polymerization (ROMP)[1] catalyst which preferentially assembles a mixture of cyclooctene and norbornene into an alternating copolymer. While there have been reports of regular copolymerizations, highly selective examples are uncommon outside of free-radical polymerization, with the 1: 1 alternating copolymers of ethylene and carbon monoxide,[2] or of epoxides and carbon ...
