Abstract

Palladium(0)-catalyzed arylation of 1H-1,2,3-benzotriazole (BTA) in DMF at 150°C in the presence of copper salt with arylhalides proceeds regioselectively at N-1 position. Best result has been obtained with the PdCl2(dppe) as catalyst and the Cu(II) phenylcyclopropylcarboxylate as co- catalyst.
