1,2,3-Triazole derivatives were synthesized in one-pot procedure via three-component reaction between organic halides, aromatic alkynes and sodium azide in the presence of 0.5 mol% Silica-immobilized NHC–Cu(I) catalyst. The catalyst showed high catalytic activity and 1,4-regioselectivity for the [3 + 2] Huisgen cycloaddition in water as a green solvent. This procedure has advantages that without the...
A new fluorous nano-palladium catalyst was prepared and characterized. The catalytic activity of the catalyst has been evaluated for the Suzuki reaction of aryl halides and aryl boronic acids to afford the corresponding products in high yields. The reaction proceeded smoothly in the presence of 0.1 mol% catalyst in EtOH/H2O at room temperature. In addition, the catalyst could be recovered by fluorous...
