Abstract
An efficient metal-free sulfenylation of indoles with disulfides has been developed, leading to 3-arylthioindoles in moderate to excellent yields. Furthermore, bromosulfenylation of indoles with di- sulfides has been realized for the first time provid- ing a new family of 2-bromo-3-arylthioindole deriv- atives in good yield by the one-pot construction of C Sa nd CBr bonds. It is noteworthy that the system enables the use of both the RS moieties in RSSR and shows a broad functional group toler- ance.
