摘要： Functionalized cyclic olefins and methods for making the same are disclosed. Methods include template-directed ring-closing metathesis ('RCM') of functionalized acyclic dienes and template-directed depolymerization of functionalized polymers possessing regularly spaced sties of unsaturation. Although the template species may be any anion, cation, or dipolar compound, cationic species, especially alkali metals, are preferred. Functionalized polymers with regularly spaced sites of unsaturation and methods for making the same are also disclosed. One method for synthesizing these polymers is by ring-opening metathesis polymerization ('ROMP') of functionalized cyclic olefins. The metathesis catalysts for both RCM and ROMP reaction are ruthenium or osmium carbene complex catalysts of formula (I) where M is Os or Ru; R and R1 each may be hydrogen, C¿2?-C20 alkenyl, C2-C20 alkynyl, C1-C20 alkyl, aryl, C1-C20 carboxylate, C1-C20 alkoxy, C2-C20 alkenyloxy, C2-C20 alkynyloxy, aryloxy, C2-C20 alkoxycarbonyl, C1-C20 alkylthio, C1-C20 alkylsulfonyl or C1-C20 alkylsulfinyl; X and X?1¿ may be any anionic ligand; and L and L1 may be any neutral electron donor.
