The well defined, conveniently accessible and coordinatively unsaturated allenylidene complexes [RuCl2(CC CPh2)(PCy3)2] and [Ru2Cl4(CCCPh2)(PCy3)(η-MeC6-H4Pri-4)] are highly effective catalysts for the ambient temperature ring-closure metathesis of α,Ï-dienes and dienynes, illustrated by the facile and high yielding formation of variously functionalised 5, 6, 7, 8, 15, 16 and 18 membered mono- and bi-cyclic ring systems.
定义明确、易于获得且配位不饱和的亚烯基配合物 [RuCl2(CC CPh2)(PCy3)2] 和 [Ru2Cl4(CCCPh2)(PCy3)(Î--MeC6-H4Pri-4)] 是δ、二烯烃和二
炔烃的高效催化剂,可方便地高产形成各种官能化的 5、6、7、8、15、16 和 18 分子单环和双环系统。
