A metal-free and solvent free click-chemistry procedure has been revealed for the synthesis of 4-trifluoroacetyl-1,2,3-triazoles from corresponding azides and alkyne with high yield and selectivity. The pure products could be easily obtained via crystallization of the reaction mixture (standing for 1 day). Among the 4-trifluoroacetyl-1,2,3-triazoles, 3ba showed the best anticancer activity against HepG2 cell with IC50 of 0.0267 μmol/ml. This method has the advantages of less pollution, low cost, simple treatment and more efficiency.
