An efficient ultrasound-promoted thiocyanation of phenols, indoles, and anilines in the presence of N-chlorosuccinimide and NH4SCN using 1,1,1,3,3,3-hexafluoro-2-propanol as the solvent has been developed. The major features of the present protocol include the mild reaction conditions, short reaction times, good to excellent yields, and broad substrate scope. Moreover, scale-up synthesis can be achieved and the solvent can be easily recovered and reused.

A simple and efficient protocol for the electrophilic thiocyanation of indoles and aromatic amines with thiourea/NCS/NH4SCN system has been developed. The major features of the present procedure are the mild conditions, good yields, short reaction times, and the use of inexpensive and readily available organocatalyst. Moreover, N-chlorosuccinimide (NCS) was found to be indispensable, and thiourea could greatly promote the reaction.
