Methods for the thiocyanation of N-activeted arenes (arylamines and anilines) and N-bearing heteroaromatic compounds (indoles, indolines, pyrroles, carbazoles, quinolines, isatins and oxindoles) have been discussed in this article. The general procedure which has been reported is using an oxidant/thiocyanation agent system. Based on oxidant type the methods classified on 6 parts. At the end the mechanistic aspects of the route have been discussed.
