1-polyfluoroaryl-1,2,3-triazoles were synthesized in moderate to good yields by an efficient copper-catalyzed one-pot three-component reaction of polyfluoroarenes, sodium azide, and terminal alkynes. The method involves a polyfluoroarylated azide intermediate produced in situ by the selective CF bond cleavage of polyfluoroarene with sodium azide.

bifunctional silica‐based solid catalyst that possessed an ionicliquid tail and a metal acetylacetonate moiety was prepared through a mild Lewis‐acid‐catalyzed ring‐opening reaction with a thiol‐functionalized silica. The surfactant‐combined silica‐supported metal acetylacetone catalysts displayed excellent catalytic activity in water for a range of reactions. The solid catalyst was also shown to be recyclable
