摘要：

Indoles 1a-f and carbazoles 3a-c on treatment with ammonium thiocyanate on montmorillonite K10 clay at 80degreesC furnished the corresponding 3-thiocyanato derivatives 2a-f and 4a-c in good to high yields. Skatole 5 furnished the dimeric oxindole 6, which resulted from autoxidation. (C) 2003 Elsevier Ltd. All rights reserved.
