convenient method for the synthesis of 3-methylthioindoles has been established which does not use smelly compounds such as thiol derivatives. The method, which introduces an alkyl- or arylthio-group into the C(3)-position of the indole skeleton, was extended to the direct introduction of a methylthio or bromo group at the C(2)-position using 3-methylthioindoles. No dimerization occurred, and the reaction
Nickel or iron salts catalyzing the selective synthesis of 3,3‐indolyl disulfide (diselenide) and 3,3‐indolyl thioether (selenide) directly from indole through C−H activation are reported. The effect of iodine element was beneficial in the novel metal‐catalyzed circulation system. A wide variety of functional groups could be tolerated under the reaction conditions.

Xtalfluor-E reacts with amine bases to form Lewisadducts which when combined with indoles afforded a simple and regioselective synthesis of di-indole sulfides as well as di-indole diethyl amino sulfonium by electrophilic aromatic substitution (SEAr).
