Studies on the catalysis of the reaction of organotin phenoxides with diethyl azodicarboxylate by lithium perchlorate

Organotin phenoxides react at room temperature with diethyl azodicarboxylate in diethyl ether, in the presence of lithium perchlorate, give the corresponding ring-aminated phenols in excellent yield. (C) 2002 Elsevier Science B.V. All rights reserved.
