Copper/HP20: Novel and Polymer-Supported Copper Catalyst for Huisgen Cycloaddition
摘要:
A polymer-supported copper catalyst (Cu/HP20) is easily prepared in water and effectively catalyzed the Huisgen cycloaddition between azides and terminal alkynes.

Synthesis, characterization, and application of copper-hydroxyacetophenone thiosemicarbazone complex immobilized on silica-coated magnetite nanoparticles (FeO@SiO-HAT-Cu(I)) as a novel magnetically retrievable nanocatalyst for the three-component synthesis of 1,4-disubstituted 1,2,3-triazoles are described. [Display omitted]
We have developed an environmentally friendly and highly efficient solvent-free Cu(I)-catalyzed azide-alkyne cycloaddition (CuAAC) reaction using a polymer-supported copper catalyst (Cu/HP20). Substrates poorly soluble in common organic solvents are also applicable to the present cycloaddition reaction without any solvents and provide the corresponding 1,4-triazole in high yields.
