An Efficient One-pot Three-component Reaction to Produce 1,4-Disubstituted-1,2,3-triazoles Catalyzed by a Dicopper-substituted Silicotungstate
2008
The dicopper-substituted γ-Keggin silicotungstate with bis-μ-1,1-azido ligands TBA 4 H 2 [γ-SiW 10 O 36 Cu 2 μ-1,1-N 3 )2] (TBA = tetrabutylammonium) could act as an effective homogeneous precatalyst for the one-pot synthesis of various kinds of 1,4-disubstituted-1,2,3-triazole derivatives from organic halides, NaN 3 , and alkynes.
