A chemoselective S-arylation reaction of thio-oxindoles with arynes is presented. The reaction was performed under mild conditions and provided a straightforward synthesis of 2-(arylthio)indolenines in good to excellent yields. Besides, this simple operat

The rapid and efficient KI/H2O2-mediated 2-sulfonylation of substituted indoles and N-methylpyrrole was established. The corresponding 2-sulfonylation products are synthesized from readily available sulfur sources, namely arylsulfonyl hydrazides, 4-methylbenzenesulfinic acid and sodium 4-methylbenzenesulfinate in good to excellent yields in only 5 min. Moreover, the aqueous solution of hydrogen peroxide is used as both oxidant and solvent. Mechanistic studies demonstrated that 2,3-diiodoindoline was the main sulfonylation intermediate.

A convenient procedure is developed for the preparation of 2-sulfonylindoles from indoles and sodium sulfinates catalyzed by KI in water. This environmentally benign 2-sulfonylation of indoles proceeds efficiently under mild conditions, affording the products with high regioselectivity and in moderate to good yields.
