Reaction of Diaryliodonium Salts with Potassium Alkyl Xanthates as an Entry Point to Accessing Organosulfur Compounds.

Preparation of S-aryl xanthates via transition-metal-catalyzed or SNAr reactions is complicated by their further transformations under the utilized conditions. In contrast, S-arylation of potassium O-alkyl xanthates with diaryliodonium salts proceeds under mild conditions, enabling access to substituted S-aryl xanthates. The method exhibits good functional group tolerance and can be applied to the late-stage C-H functionalization of drug molecules. Divergent transformations of the resulting S-aryl xanthates provide rapid access to a range of medicinal chemistry-relevant organosulfur compounds.
