dichloromethane to give the acyclic adducts 6–10 in 64–91% yield. The orientation effects are in contrast to the predictions of perturbational molecular orbital theory and can be explained on the basis of steric effects.
在二氯甲烷中存在氯化锌/醚的情况下,二烯基氯化物1-5与异丁烯反应,以64-91%的产率得到无环加合物6-10。取向效应与微扰分子轨道理论的预测相反,并且可以基于空间效应进行解释。
