were unexpectedly obtained by treatment of these salts with base. Methylation and benzylation of the thione 8 provided the 5-methylthio-1,3,2-dithiazol-1-ium 9 and 4-benzylthio-1,3,2-dithiazol-1-ium 12 salts, which on treatment with base afforded 5-methylthio-10 and 5-benzylthio-1-λ4δ2,3,2-dithiazole-4-thione 13 respectively; further alkylation provided a route to symmetrical difunctionalised cations
通过三甲基硅烷基叠氮化物与1-氯乙烷-1,2-双的反应制备了1,3,2-二噻唑-1-氯化物6和5-氯-1,3,2-二噻唑-1-氯化物7(亚磺酰氯)和1,2-二氯乙烷-1,2-双(亚磺酰氯)。相应的中性1-λ 4 δ 2,3,2二噻唑-4-硫酮8和5-氯-1-λ 4 δ 2,3,2二噻唑-4-硫酮18被意外地治疗这些盐的获得与基地。硫酮8的甲基化和苄基化提供了5-甲硫基-1,3,2-二噻唑-1-ium 9和4-苄硫基-1,3,2-二噻唑-1-ium 12盐,其用碱处理,得到5-甲硫基10和5-苄硫基-1-λ 4 δ 2,3,2二噻唑-4-硫酮13分别; 进一步的烷基化提供了一条通往对称双官能化阳离子的途径,例如4,5-二甲硫-1,3,2-二噻唑-1-碘化碘11。的dithiazolium酰氯处理7与氨或苯胺导致5-氨基19和5-苯胺基1-λ 4 δ 2,3,2二噻唑-4-硫酮20分别。
