Indoles, oxindoles and aromatic amino compounds undergo smooth thiocyanation with ammonium thiocyanate in the presence of anhydrous FeCl 3 in dichloromethane under mild conditions to afford the corresponding 3-indolyl and 4-aryl thiocyanates, respectively, in high yields with excellent selectivity. The use of ferric chloride makes it quite simple, more convenient and practical. This new method offers
