A Cp2TiCl2-catalyzed intermolecular homocyclomagnesiation of O-containing 1,2-dienes and cross-cyclomagnesiation of O-containing 1,2-dienes with aliphatic 1,2-dienes of cyclic and acyclic structure have been accomplished using Grignard reagents, which led to mono- and bicyclic organomagnesium compounds in 61–94% yields.
使用格氏试剂,成功实现了以Cp2TiCl2为催化剂的含氧1,2-二烯的分子间同环镁化反应以及含氧1,2-二烯与具有环状和非环状结构的脂肪族1,2-二烯的交叉环镁化反应,产率分别为61-94%,得到了单环和双环有机镁化合物。
