2,4,6-trinitrotoluene + 2 NADPH + 2 H+ = N-hydroxy-2-methyl-3,5-dinitroaniline + 2 NADP+ + H2O
The amount of N-hydroxy-2-methyl-3,5-dinitroaniline is larger than the amount of N-hydroxy-4-methyl-3,5-dinitroaniline formed. In a further nonenzymatic reaction nitrite is released and N-(2-methyl-3,5-dinitrophenyl)-N-4-methyl-3,5-dinitrophenyl-hydroxylamine and eventually N-(2-methyl-3,5-dinitrophenyl)-N-4-methyl-3,5-dinitroaniline are produced. In adidtion the aromatic ring of 2,4,6-trinitrotoluene is susceptible to nucleophilic attack by hydride ions to form Meisenheimer complex intermediates (monohydride and dihydride complexes) which also form the secondary diaryl hydroxylamines and the secondary diarylamine with release of nitrite

2,4,6-trinitrotoluene + 2 NADPH + 2 H+ = N-hydroxy-4-methyl-3,5-dinitroaniline + 2 NADP+ + H2O
The amount of N-hydroxy-4-methyl-3,5-dinitroaniline is larger than the amount of N-hydroxy-2-methyl-3,5-dinitroaniline formed. In a further nonenzymatic reaction nitrite is released and N,N-bis-(3,5-dinitrotolyl)-hydroxylamine and eventually N,N-bis-(3,5-dinitrotolyl)-amine are produced. In addition the aromatic ring of 2,4,6-trinitrotoluene is susceptible to nucleophilic attack by hydride ions to form Meisenheimer complex intermediates (monohydride and dihydride complexes) which also form the secondary diaryl hydroxylamines and the secondary diarylamine with release of nitrite
