It is shown (1) that in the most reactions of anilines 2 with 1-sulfonyl-2,2-dimethylaziridines 1 both isomeric products 3 and 4 are formed, (2) that the "normal" product 4 obtained by attack on position 3 of 1 usually arises in a small or negligible amount that seems to decrease with decreasing basicity of 2, and (3) that the amount of 4 strongly increases with increasing steric demand of 2.Formation of 4 is explained by a lag of bond making in SN2. +"--"+ N-Aryl-N'-sulfonyl-gem-dimethylethylenediamines, 1-Sulfonyl-2,2-dimethylaziridines, Regioselectivity of Nucleophilic Ring Opening, Steric Hindrance Effect, Basicity Effect
