The electrophilic sulfenylation of a series of indoles and pyrroles with arylsulfenamides in the presence of phophorus(V) oxohalide has been studied. It has been shown that arylsulfenylation of indoles led to products with substitution at position 3, while in the case of pyrrole it occurred at position 2.

We present here the synthesis of sulfenyl pyrroles by copper-catalyzed sulfenylation of pyrroles with organic disulfides or thiols. The direct sulfenylation of pyrroles with organic disulfides has been accomplished in the presence of 3 mol % of CuI in DMSO at 110 °C under air atmosphere. In the other hand, sulfenylation of pyrroles with thiols were performed in the same solvent and temperature, however

A novel sulfenylation method induced by aromatization of quinone mono-O,S-acetals is described. These sulfenylation reagents readily react with silyl enolethers or electron rich aromatic compounds to give sulfenylation products under mild conditions. In particular, O,S-acetal 2j, which possesses a pentafluorophenylthio function, is the most effective reagent from the standpoint of the adaptability for various substrates.
