"WebCan alkynes be polymerised? The term 1-alkyne polymerization refers to a process in which a terminal alkyne undergoes, similar to the ROMP process of a cyclic olefin, a [2 + 2] cycloaddition to a metal carbene (alkylidene).This can proceed via α- or β-insertion of the alkyne into the metal–carbon double bond (Scheme 4).
