Synthesis of functionized N-arylbenzotriazoles via palladium catalyzed intramolecular amination

The functionalized benzotriazoles are prepared by palladium catalyzed intramolecular amination of 2-bromodiaryltriazene. By screening the reaction conditions, such as ligand, solvent, base and reaction concentration, the optimal reaction conditions were o

L-Proline N-oxide dihydrazides as an efficient ligand for cross-coupling reactions of aryl iodides and bromides with amines and phenols

A novel catalytic system based on L-proline N-oxide/CuI was developed and applied to the cross-coupling reactions of various N- and O- nucleophilic reagents with aryl iodides and bromides. This strategy featured in the employment of an-proline derived dihydrazides N-oxide compound as the superior supporting ligand. By using this protocol, a variety of products, including N-arylimidazoles, N-arylpyrazoles, N-arylpyrroles, N-arylamines, and aryl ethers, were synthesized with up to 99% yield.

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.
