Electron-rich aza-aromatic compounds such as indoles is structures of particular interest and importancein organic chemistry. A useful procedure for the preparation of new 3-sulfenyl indole derivatives using S-alkyl or S-arylthiophthalimides as sulfenylating agents and poly(N, N′-dibromo-N-ethyl-naphthyl-2,7-disulfonamide) as novel catalyst is described. The method represents an efficient prepa...
