A novel electrochemical cross-coupling method for the
synthesis
of thiocyanates via the direct cyanation of readily
available thiophenols or thiols with trimethylsilyl cyanide (TMSCN)
was developed. This approach was also suitable for selenols. External
oxidant-free, transition-metal-free and mild operating conditions
were the main advantages of this protocol. A series of thiocyanates
and selenocyanates could be obtained in moderate to high yields.
