Reactions of 1-(phenylsulphonylmethyl)benzotriazole with some nitroarenes
摘要:
Treatment of nitroarenes 2 - 6 with 1-(phenylsulphonylmethyl)benzotriazole 1 in the KOH - DMSO base-solvent system at room temperature results in cleavage of the phenylsulphonyl group, while the t-BuOK - DMF system at low temperature promotes oxidation of the reaction intermediates.

cleavage of the phenylsulphonyl group, whereas the t-BuOK/DMF system at low temperature promotes to a greater extent oxidation of the σ-adducts. When 1-(phenylsulphinylmethyl)azoles were used for the reaction only elimination of the phenylsulphinyl group was observed.
