Abstract

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.

Abstract

Cu(BTC)-MOF catalyzed one-pot, three-component reaction of terminal alkynes, halides and sodium azide to form 1,4-disubstituted-1,2,3-triazoles was investigated. It was conducted in methanol under room temperature with good to excellent product yields. The Cu(BTC)-MOF catalyst could be easily recovered by filtration and be reused at least three recycles with no significant decrease in the yield. The method was demonstrated to be a truly green process with sustainability and economics.
