Diazonium ions have been immobilized onto an ion-exchange resin support and were subsequently reacted with sodioindole in dry tetrahydrofuran to give the N-arylazoindole. The solid phase diazocoupling reaction appears to be the only method for the preparation of the target molecules. (C) 1997 Elsevier Science Ltd.
