In living ring-opening metathesis polymerization (ROMP), a transition-metal–carbene complex polymerizes ring-strained olefins with very good control of the molecular weight of the resulting polymers.
Olefin metathesis reactions are metal-mediated carbon–carbon (C–C) double bond exchange processes, 1, 2 which were discovered in the mid 1950s. Chauvin proposed the commonly accepted mechanism for ...
