[CpCo(CO)2] catalyzes the cycloisomerization of 1,n-enynes to afford selectively five- and six-membered ring systems in high yields. The factors governing the cyclization have been explored and we have discovered that the reaction associates two different, but complementary, reactivities of the cobalt(I) complexes. By a judicious choice of the substitution of the enyne, it was also possible to isolate
[CpCo(CO)2]催化1,n-烯炔的环异构化,以高收率选择性提供五元和六元环系统。已经探索了控制环化的因素,我们发现该反应与钴(I)配合物的两个不同但互补的反应性相关。通过明智地选择烯炔的取代,也可能分离出由环戊烯钴产生的环丁烯
