Acetylacetone copper (II) catalytic synthesis method for 1,2,3 triazole chemical compounds

The invention discloses an acetylacetone copper (II) catalytic synthesis method for 1,2,3 triazole chemical compounds, and belongs to the field of the synthetic technology of the 1,2,3 triazole chemical compounds. According to the technical scheme, azide and end group compound serve as raw materials, the acetylacetone copper (II) serves as a catalyzer, water serves as a solvent, stirring and reacting are conducted, complete reaction of the raw materials is monitored by TLC, ethyl acetate is added to extract a reaction product, water phase and organic phase are filtered at the same time, a filter cake is cleaned by using the ethyl acetate to obtain the catalyzer, namely, the acetylacetone copper (II) to be recycled repeatedly, and skimming is conducted on filter liquor to obtain the organic phase of the 1,2,3 triazole chemical compound. The catalyzer is cheap, the preparation method is simple, the catalytic efficiency is high, reutilization can be achieved, the catalyzer is reproducible, the reproductive catalyzer still has high catalytic activity, and the yield of the product is equal to the catalyzer before reproduction is conducted.
