Enyne ring closing metathesis has been used to synthesize functional group carrying metathesis catalysts from a commercial (Ru-benzylidene) Grubbs' catalysts. The new Grubbs-type ruthenium carbene was used to synthesize living heterotelechelic ROMP polymers without any intermediate purification. Olefin metathesis with a mono substituted alkyne followed by ring closing metathesis with an allylic ether provided efficient access to new functional group carrying metathesis catalysts. Different functional benzylidene and alkylidene derivatives have been investigated in the synthesis of heterotelechelic polymers in one pot.

通过闭环烯炔复分解作用的功能复分解催化剂：活性异遥爪聚合物的一锅法

Enyne 闭环复分解已用于从商业（Ru-亚苄基）Grubbs 催化剂合成带有官能团的复分解催化剂。新的 Grubbs 型钌卡宾用于合成活性异遥爪 ROMP 聚合物，无需任何中间纯化。用单取代炔烃进行烯烃复分解，然后用烯丙基醚进行闭环复分解，为获得带有新官能团的复分解催化剂提供了有效途径。不同功能的亚苄基和亚烷基衍生物已经在一锅合成异远螯聚合物中进行了研究。
