Despite their long-known photochemical properties and their industrial value, the use of nitroarenes as a productive photochemical handle in organic synthesis has remained relatively unexplored. More specifically, the photochemical formation of nitrogen-sulfur bonds from nitroarenes remains to be demonstrated. Herein, we report the design and application of a sulfinate–nitroarene electron donor–acceptor
Fenton's reagent in dimethyl sulphoxide: an unusual sulphonylating system. X-Ray crystallographic analysis of 4-N,N-dimethylamino-N,N-dimethane-sulphonylaniline
On treatment with Fenton'sreagent in dimethylSulphoxide nitrosoarenes form sulphonylate products, while the expected N,O-dimethylated hydroxylamine is isolated only in the case of nitrosobenzene in low yield. Nitrosobenzene and 4-cyanonitrosobenzene lead to N-sulphonylhydroxylamines while 4-nitroso-N,N-dimethylaniline and 1-nitroso-2-phenyl-3-acetylindolizine give sulphonamides and ring-sulphonylated
