Ambident Reactivities of Methylhydrazines

Abstract

Kinetics versus thermodynamics: Methyl groups increase the nucleophilic reactivity of the substituted position of hydrazines and reduce the nucleophilicity of the adjacent nitrogen center. As a result, the tertiary nitrogen atom of 1,1-dimethylhydrazine is 3000 times more reactive than the NH2 group, but under thermodynamic control substitution of an NH2 proton occurs (see picture).
