Abstract

Some 1H-benzotriazoles have been synthesised in good yields in short times by reaction of ophenylenediamine with sodium nitrite in acetic acid under ultrasound irradiation. Also, the ultrasoundassisted preparation of 1-acylbenzotriazoles is described.

Keywords: Benzotriazoles, acylbenzotriazoles, ultrasound irradiation, sonochemistry, heterocycles
