摘要：

Magnetically recoverable and reusable CuFe2O4 nanoparticles are shown to be highly efficient catalysts for the one-pot synthesis of biologically important 1,4-diaryl-1,2,3-triazoles starting from boronic acids, sodium azide, and acetylenes. The use of aqueous reaction medium at room temperature, the low cost and facile recovery of the catalyst by application of an external magnetic field, and consistently high catalytic efficiency for at least three consecutive cycles renders the protocol operationally attractive.
