摘要:
The reactions of 2,4,6-trinitrotoluene with arenethiols in the presence of inorganic bases in dipolar aprotic solvents led to the replacement exclusively of the ortho-nitro group to form 2-arylthio-4,6-dinitrotoluenes. Substitution, oxidation, and reduction of the latter and their transformation products provided the basis for the preparation of mono- and di-ortho-S-substituted nitroluenes and aminotoluenes. Factors favoring the regiospecificity Of ortho-substitution in 2,4,6-trinitroluene are discussed.
