用1,3-维咪唑-2-基苄基钌-苄基1制备了许多杂环化合物，收率很高。该催化剂对一些用Grubbs催化剂不能环化的受阻杂二烯的合环复合反应表现出更高的活性。扩大了烯烃再分解的范围。
[GRAPHICS]A number of heterocycles have been prepared in very good yields using 1,3-dimesitylimidazol-2-ylidene ruthenium benzylidene 1. This catalyst displays increased activity for ring closing metathesis of some hindered heterodienes which did not cyclize using the Grubbs catalyst 2. The scope of the olefin metathesis has been expanded.
