四氢噻唑硫酮(tetrahydrothiazole-2-thione,简称TTT)与羧酸反应,可获得高产率的黄色晶状酰化物。该酰化物易于还原,从而可将羧酸转变为相应的醛类。它还可用于多肽、酰胺类合成及产生烯酮。其X射线结构分析尚未见报道。我们制备了苯甲酰-四氢噻唑-2-硫酮单晶,并以此化合物为模型进行了X射线衍射分析,结果进一步验证了其结构为N-苯甲酰-四氢噻唑-2-硫酮(1)而不是相应的苯甲 Tetrahydrothiazole-2-thione (TTT) is reacted with a carboxylic acid to obtain a yellow crystal acylate in a high yield. The acylate is easily reduced so that the carboxylic acid can be converted to the corresponding aldehyde. It can also be used for polypeptide, amide synthesis and production of ketene. Its X-ray structure analysis has not been reported yet. We prepared the benzoyl-tetrahydrothiazole-2-thione single crystal, and using this compound as a model for X-ray diffraction analysis, the results further verify the structure of N-benzoyl-tetrahydrothiazole -2- Thione (1) instead of the corresponding benzyl
