This manuscript is dedicated to the (Late) Prof. Alan R. Katritzky for his contributions to benzotriazole chemistry.

Abstract

N-Acylbenzotriazoles are achieved in good yields from the corresponding carboxylic acids by using only 0.35 equivalent of trichloroisocyanuric acid and 1.2 equivalents of PPh3. The salient features of the developed reaction path include an economic, facile, base-free, and equally useful method in milligram to gram scale.
