An electrochemical direct cyanation of readily available thiophenols or thiols with trimethylsilyl cyanide (TMSCN) provides thiocyanates under mild operating conditions. This oxidant- and transition-metal-free cross-coupling method is also suitable for selenols.

Thioethers can be converted to thiocyanates via fluorium-initiated dealkylative cyanation in the presence of selectfluor as the oxidant and trimethylsilyl cyanide as the cyanation reagent. This method is user-friendly, operationally simple, and step-economical.
