Recent studies of the addition reactions of the butenylmagnesium bromide have indicated that the butenyl Grignard reagent is probably best formulated as being exclusively crotylmagnesium bromide. The almost invariable formation of products containing α-methylallyl groups in carbonyl addition reactions has been suggested as due to the operation in the addition process of a six-membered cyclic mechanism
最近对丁烯基溴化镁的加成反应的研究表明,丁烯基格氏试剂可能最好只配制成巴豆基溴化镁。羰基加成反应中几乎不变地形成含有α-甲基烯丙基的产物,这是由于六元环加成过程中的操作。
