Difluoromethylthiolation of aryldiazonium salts under photocatalytic conditions with a shelf-stable, easily prepared and inexpensive reagent, PhSO2SCF2H was described. A variety of difluoromethylthioethers were obtained utilizing aryldiazonium salts containing different functional groups. Aryldiazonium salts with a heteroarene moiety were tolerated. Fluorescence quenching experiments indicated that both oxidative and reductive quenching cycles occurred during this process.

A simple and efficient visible-light photoredox one-pot method for difluoromethylation of phenols and thiophenols has been developed. The protocol uses commercially available, inexpensive, and easy handling difluorobromoacetic acid as the difluoromethylating agent, and the diverse O- and S-difluoromethylated products were prepared in good yields with tolerance of many functional groups.
