Abstract A simple and convenient method for the synthesis of thiophosphates by coupling of phosphites with thiols under mild conditions has been developed. The reactions were promoted by trichloroisocyanuricacid (TCCA) and were carried out at room temperature in a one-pot two-step procedure within 20 min. A variety of substrates was tolerated in this method. Notably, both aryl and alkyl thiols could

approach for the synthesis of aryl sulfides through the coupling of thiols with Grignardreagents in the presence of N-chlorosuccinimide is described. The sulfenylchlorides were formed when thiols were treated with N-chlorosuccinimide, and the resulting sulfenylchlorides were then directly reacted with Grignardreagents to provide aryl sulfides in good to excellent yields under mild reaction conditions.

sulfenyl and selenyl chlorides to afford 1,3‐chlorochalcogenated products. The transformation is achieved by a merged iminium–enamine activation. The enantioselective desymmetrization reaction, leading to three adjacent stereocenters, furnished the target products in complete regioselectivity and moderate to high diastereo‐ and enantioselectivities (d.r. up to 15:1 and e.r. up to 93:7).
