An efficient TBAI (tetrabutylammonium iodide)-mediated C-H sulfenylation of arenes with arylsulfonyl hydrazides in dipropylene glycol dimethyl ether (DPDME) was described. Various electron-rich arenes were applicable in the reaction, such as naphthylamine, naphthol, aniline, indole, pyrrole, and imidaz o [1,2, 2(a)] pyridine. A wide range of the aryl sulfides were obtained with good functional group

A copper‐catalyzedthree‐component (arenes, iodohydrocarbon, and sulfur powder) synthesis of substituted aryl sulfides has been developed. Water is used as the green solvent in a simple and environmentally friendly procedure. Various functional groups attached to the substrates were well tolerated in this process to afford the corresponding products in moderate to good yields.
