| titleOfInvention | Preparation method of 4-thiocyano-1, 4, 5-trisubstituted 1,2, 3-triazole |
| abstract | The invention belongs to the technical field of organic synthesis, and provides a preparation method of 4-thiocyano-1, 4, 5-trisubstituted 1,2, 3-triazole, which comprises the following steps: in an organic solvent, under the action of a tetra-acetonitrile copper hexafluorophosphate catalyst, catalyzing an alkyne compound in a thiocyanate group to react with an organic azide compound to prepare the 4-thiocyanate substituted 1,4, 5-trisubstituted 1,2, 3-triazole. The preparation method of the 4-thiocyanate substituted 1,4, 5-trisubstituted 1,2, 3-triazole and the preparation method of the 4-sulfo-1, 4, 5-trisubstituted 1,2, 3-triazole have mild reaction conditions, and the yield of the product is not lower than 55%. The preparation method has mild and green reaction conditions and high reaction efficiency, and meets the requirement of large-scale production. |
