Cu-catalyzed arylation of 1-acyl-1H-1,2,3-Benzotriazoles via C–N activation

An efficient copper-catalyzed arylation reaction of 1-acyl-1H-1,2,3-benzotriazoles with diaryliodonium salts via C–N activation is explored. The reaction is conducted regioselectively to form 1-aryl-1H-1,2,3-benzotriazoles in MeCN at 80 °C in the presence of cesium carbonate. 29 examples are given with the product yield of up to 84%. The probable reaction mechanism is proposed.

TCT-mediated synthesis of N-acylbenzotriazoles in aqueous media

The synthesis of N-acylbenzotriazoles has been demonstrated by the 2,4,6-trichloro-1,3,5-triazine (TCT)-mediated condensation of carboxylic acids with 1H-benzotriazole in aqueous media. In saturated aqueous sodium bicarbonate, TCT was found to be relatively stable and functioned as an efficient acid activator in the acyl transfer process. This operationally simple and economic method allows the scalable synthesis of N-acylbenzotriazoles in good to excellent yields.
