Abstract

N-Alkyl-Np-toluenesulfonyl-2, 4, 6-trinitrobenzenesulfenamides. A solution of 3.5 mmol of 2, 4, 6-trinitrobenzenesulfenyl chloride in 10 ml of benzene was added to a magnetically stirred suspension of 4 mmol of a silver ialt of N-alkyl-p-toluenesulfonamide in 30 ml of benzene and the mixture was stirred at room temperature for 48 h. After filtration of the solid, the solution was evaporated and the residue chromatographed on silica gel with benzene- ...
