A series of bis-arylsulfenylated indoles (10), benzofurans (3), and benzothiophenes (3) and of monosulfenylated indoles (5), 12 of which are novel, were prepared in good yields via a Cu-catalysed direct sulfenylation of benzoheterocycles with arylsulfonyl hydrazides. Sulfonothioates are probably the major thiolated intermediates in this transformation.

3-(Alkylsulfanyl)- and 3-(arylsulfanyl)indoles were efficiently prepared by the reaction of indoles with sodium sulfinates mediated by iodine-PPh 3 in ethanol. The salient features of the present protocol are simplicity, high efficiency, non-anhydrous conditions, environmentally friendly reagents and solvent, and short reaction time.
