Metal-free, oxidative decarboxylation of aryldifluoroacetic acid with the formation of the ArS–CF2 bond

A metal-free, oxidative decarboxylative reaction of aryldifluoroacetic acids with diaryl disulfides or thiols under mild reaction conditions has been developed. This is an efficient and straightforward radical cross-coupling method for the synthesis of diverse aryldifluoromethylthio ethers in moderate to excellent yields.
