Some 1H-benzotriazoles have been synthesised in good yields in short times by reaction of o-phenylenediamine with sodium nitrite in acetic acid under ultrasound irradiation. Also, the ultrasound-assisted preparation of 1-acylbenzotriazoles is described.Univ São Paulo, Lab Sintese Mol Bioativas, Dept Farm, Fac Ciencias Farmaceut, BR-05508300 São Paulo, BrazilUniv São Paulo, Ctr Capacitacao & Pesquisa Meio Ambiente, Inst Quim, São Paulo, SP, BrazilUniversidade Federal de São Paulo, Dept Biofis, São Paulo, SP, BrazilUniversidade Federal de São Paulo, Dept Biofis, São Paulo, SP, BrazilWeb of Scienc
