Abstract

Abstract 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.
