  Efficient hydrolysis of dithioacetals by the N-fluoro-2,4,6-trimethylpyridinium triflate-water system

  摘要：

  Dithioacetals including 1,3-dithianes and 1,3-dithiolanes are efficiently cleaved by the title reagent system to the parent carbonyl compounds. The cleavage of diprotected symmetrical alpha-diketones and p-phenylene-diketones gives monoketones in good yields. Amide, 1,3-dioxolane, disulfide, ester, ether, hydroxy, nitrile, nitro, and sulfide functions are relatively stable under the cleavage conditions but thiols are oxidized to disulfides.

• The Reaction of 2-Ethoxy-1,3-oxathiolane with Carbonyl Compounds in the Presence of ZnCl₂or HgCl₂

  In the reaction of 2-ethoxy-1,3-oxathiolane with carbonyl compounds in the presence of ZnCl2 or HgCl2, it has been found that only the breaking of the endocyclic bond (C–O or C–S bond) occurs, while the breaking of the exocyclic C–O bond to give the 1,3-oxathiolan-2-ium ion is unfavorable. This behavior is different from that of 2-ethoxy-1,3-dithiolane, in which the breaking of the endocyclic C–S bond

  在 ZnCl2 或 HgCl2 存在下，2-乙氧基-1,3-氧杂硫杂环戊烷与羰基化合物反应，发现仅发生内环键（C-O 或 C-S 键）断裂，而环外 C-O 键断裂产生 1,3-oxathiolan-2-ium 离子是不利的。这种行为不同于 2-乙氧基-1,3-二硫戊环，其中环内 C-S 键通过 HgCl2 和外环 C-O 键发生断裂，通过 ZnCl2。
