3-benzotriazole, with activated aryl halides in a medium of aromatichydrocarbons under conditions of phase transfer catalysis with the use of inorganic bases and cetyltrimethylammonium bromide as a phase-transfer catalyst was studied. Arylation affords bothN(1)- andN(2)-arylation products. Their ratio depends on the nature of the base and the reactivity of the arylating agent. In the presence of catalytic
