摘要：

The metathesis catalyst 1 allows the first living cyclopolymerization of 1,6-heptadiynes. With the chiral 4-(ethoxycarbonyl)-4-(1S,2R,5S)-(+)-menthoxycarbonyl-1,6-heptadiyne highly tactic polymers with an alternating cis-trans structure and a stereoregularity of greater than 95% are obtained. Fixation of 1 on poly(2-oxazo-line) block copolymers provides access to poly(acetylene) s under aqueous conditions by micellar catalysis.
