Method for preparing 1,2,3-thiadiazole-4-carboxylic acid

The invention relates to a method for preparing 1,2,3-thiadiazole-4-carboxylic acid, which comprises: preparing 4,5-dicyano-1,2,3-thiadiazole by reaction between diaminomaleonitrile and dichloroethane; preparing 1,2,3-thiadiazole 4,5-dicarboxylic acid by the cyan-hydrolysis of 4,5-dicyano-1,2,3-thiadiazole; and preparing 1,2,3-thiadiazole-4-carboxylic acid by the decarboxylation reaction of 1,2,3-thiadiazole 4,5-dicarboxylic acid. The provided process route is high in synthesis rate of the target product, moreover, the process route can be magnified, the raw materials can be easily obtained and are cheap, and industrial production can be carried out.

Organic Heterocyclothiazenes. Part 5. Cycloaddition Reactions of Tetrasulphur Tetranitride with Highly Electron Deficient Alkynes

In contrast with previous, complex, S4N4-alkyne reactions, treatment of butynedinitrile and S4N4 is found to give 1,3,5,2,4-trithiadiazepine-6,7-dicarbonitrile (8) and 1,2,5-thiadiazole-3,4-dicarbonitrile (9) very cleanly and in high yield.Hexafluorobut-2
