Abstract
Palladium(O)-catalyzed arylation of 1H-1,2,3-benzotriazole (BTA) in wa ter at 100 degrees C with diaryliodonium salts proceeds in the presenc e of copper salt regioselectively at N-1 position. Best result has bee n obtained with the Pd(OAc)(2)(tppts)(2) as catalyst and the Cu(II) ph enylcyclopropylcarboxylate as co-catalyst. Both aryl groups from diary liodonium salt participate in the reaction. (C) 1998 Elsevier Science Ltd. All rights reserved.
