Regioselectivity of nucleophilic attack on 2,2-dimethylaziridines depends on the degree of leaving group activation: in highly activated aziridines it occurs at the methylene carbon and in less activated at the tertiary carbon. This latter abnormal ring opening is explained by an SET mechanism.
对2,2-二甲基氮丙啶的亲核攻击的区域选择性取决于离去基团的活化程度:在高度活化的氮丙啶中,它发生在亚甲基碳上,而在叔碳中活化较少。后一种异常的开环由SET机构解释。
