General description

1,1,1-Trimethylhydrazinium iodide ([(CH3)3N-NH2]I, TMHI) is widely employed as a vicarious nucleophilic substitution (VNS) reagent for various aromatic amination reactions. On reaction with silver salt, it affords the following salts: nitrate (([(CH3)3N-NH2][NO3]), perchlorate ([(CH3)3N-NH2][ClO4]), azide ([(CH3)3N-NH2][N3]), 5-amino-1H-tetrazolate ([(CH3)3N-NH2][H2N-CN4]) and sulfate ([(CH3)3N-NH2]2[SO4].2H2O).

Application

1,1,1-Trimethylhydrazinium iodide (TMHI) may be employed for the amination of 1-X-3,5-dinitrobenzenes.
