available aryl and alkyl thiocyanates were converted into the corresponding (benzenesulfonyl)difluoromethyl thioethers via the direct nucleophilic substitution of ((difluoromethyl)-sulfonyl)benzene under transition metal free conditions. Combined with various thiocyanation methods, this reaction can allow late-stage (benzenesulfonyl)difluoromethylthiolation of alkyl halides and aryldiazoniumsalts.

A new method for the cyanation of thiols and disulfides using cyanobenziodoxol(on)e hypervalent iodine reagents is described. Both aliphatic and aromatic thiocyanates can be accessed in good yields in a few minutes at room temperature starting from a broad range of thiols with high chemioselectivity. The complete conversion of disulfides to thiocyanates was also possible. Preliminary computational

Herein we report a novel C–S bond cleavage and reconstruction strategy for the synthesis of thiocyanates through direct photocatalytic S–Hbond cyanation from thiols and inorganic thiocyanate salts. In our strategy, the unprecedented example of cutting off C–S bond of SCN– to deliver the green “CN” sources is demonstrated. This transformation features nontoxic and inexpensive “CN” sources, available
