Magnetic Copper Ferrite Nanoparticles: An Inexpensive, Efficient, Recyclable Catalyst for the Synthesis of Substituted Benzoxazoles via Ullmann-Type Coupling under Ligand-Free Conditions
A novel one pot synthesis of β-hydroxy-1,4-disubstituted-1,2,3-triazoles has been developed by using CuFe2O4 nanoparticles. This protocol involves easily recyclable catalyst in water and avoids the handling of azides as they are generated in situ.
