TL;DR: DMSO could serve as an effective methylthiolation reagent for the synthesis of heterocyclic methyl thioethers in the form of a Lewis acid catalyzed reaction between heteroarenes and thiols.
Abstract: A Lewis acid (AgI, NiII, or FeII) catalyzed, CuII-mediated thiolation reaction between heteroarenes and thiols was achieved with good yield under base-free conditions. DMSO could serve as an effective methylthiolation reagent for the synthesis of heterocyclic methyl thioethers.

TL;DR: In this article, a wide range of phenols can be iodized with unprecedented selectivity in aqueous alcohol solvents by the action of a reagent prepared in situ from sodium hypochlorite and sodium iodide.
Abstract: Direct iodination of a wide range of phenols may be achieved with unprecedented selectivity in aqueous alcohol solvents by the action of a reagent preparated in situ from sodium hypochlorite and sodium iodide. Para-substituted phenols (or ortho-substituted, when the para-position is already occupied) are obtained in fair to excellent yields by simple isolation techniques. The extent of iodination is easily controlled by stoichiometry. The technique is also useful with some anilines
