A Versatile Procedure for the Preparation of Aryl Thiocyanates Using N-Thiocyanatosuccinimide (NTS)
摘要:
A mild procedure for the thiocyanation of several types of arene substrate using N-thiocyanatosuccinimide (NTS) is described. The method appears generally applicable to benzenoid substrates with a wide range of substituents, as well as to heteroaromatic analogues such as indoles and thiophenes.

An operationally simple electrochemicalmethod for the transition‐metal‐free ipso‐thiocyanation of arylboronicacids and aryl trifluoroborates has been developed. The SCN electrophile is generated in situ by anodic oxidation of thiocyanate anions, which avoids formation of salt waste and prevents unwanted side reactions arising from chemical oxidants. The reaction proceeds regiospecifically, and the
