Sulfonamides have many important biological applications, yet their synthesis often involves long reaction times under dry and non-ambient conditions. Here we report the synthesis of a large range of sulfonamides at room temperature using 4-nitrophenyl benzylsulfonate as a starting material. Sulfonamides were prepared from a wide range of aliphatic, linear, and cyclic amines, anilines, and N-methylanilines

alpha-Sulfonyl nitrodiphenylmethane derivatives undergo an autoxidation to nitrobenzophenones in the presence of solid K2CO3 and tetrabutylammonium bromide in dimethoxyethane in good yields.
