Cu(BTC)-MOF catalyzed multicomponent reaction to construct 1,4-disubstituted-1,2,3-triazoles

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. (C) 2018 Elsevier Ltd. All rights reserved.
