Organomagnesium compounds with allylic double bonds (aliyl-, methallyl- and crotylmagnesium halides and octadienediylmagnesium) react with 1,2-dienes (allene) or 1,3-dienes (butadiene, isoprene) to yield cyclohexane derivatives. Compounds of the crotylmagnesium type add predominantly in the isomeric α-methylallyl form. In addition alkylmagnesium halides with tertiary or secondary alkyl groups show
具有烯丙基双键的有机镁化合物(卤代烷基,甲代烯丙基和巴豆基卤化镁和辛二烯基镁)与1,2-二烯(丙二烯)或1,3-二烯(丁二烯,异戊二烯)反应生成环己烷衍生物。巴豆基镁类型的化合物主要以异构体α-甲基烯丙基形式添加。另外,具有叔或仲烷基的烷基卤化镁显示出对烯烃的增强的反应性。
