Title:
NOVEL PREPARATION METHOD FOR 4-THIOCYANO-1,4,5-TRISUBSTITUTED 1,2,3-TRIAZOLE
Document Type and Number:
WIPO Patent Application WO/2021/088296
Kind Code:
A1
Abstract:
A preparation method for 4-thiocyano-1,4,5-trisubstituted 1,2,3-triazole, comprising the following step: in an organic solvent, under the action of a copper hexafluorophosphate tetraacetonitrile catalyst, catalyzing a thiocyanato internal alkyne compound to react with an organic azide compound to prepare 4-thiocyanato-1,4,5-trisubstituted 1,2,3-triazole.
