  • Photofragmentation reactions of dithiolactones
    作者:Kayambu Muthuramu、Bhagavathi Sundari、Vaidhyanathan Ramamurthy

    日期:1983.1
    The occurrence of Norrish type-I α-cleavage has been established in β-dithiolactones, involving the n-π* singlet state (diradical and carbene reactive intermediates). Concerted ring expansion to a thiacarbene from the excited state is suggested to be responsible for the formation, at least in part, of one of the cyclic thioacetals. Although this α-cleavage process is similar to that of corresponding

    primarily formed CF3 adduct A followed by ring closure via the S-atom (Scheme 2). In the case of thiobenzophenones 4, complex mixtures of products were obtained including diarylmethyl trifluoromethyl sulfide 10 and 1,1-diaryl-2,2-difluoroethene 11 (Scheme 4). Obviously, competing thiophilic and carbophilic addition of the CF3 anion took place. The reaction with 9H-fluorene-9-thione (5) yielded only 9,9'-bifluorenylidene

    The reaction of 2,2,4,4-tetramethyl-3-thioxocyclobutanone S-oxide with Lawesson reagent (L. R.) afforded the corresponding 1,2,4-trithiolane. Thiopivalophenone and thiopivalophenone S-oxides reacted with L. R. at rt to give the corresponding S-sulfide, which further reacted with thiones to afford the corresponding cis-1,2,4-trithiolanes.

  • Relative Reactivities of Carbonyl and Thiocarbonyl Groups toward Dimethoxycarbene: Two New Dimethoxythiiranes
    作者:Małgorzata Dawid、Grzegorz Mloston、John Warkentin

    preferentially at the carbonyl group, rather than the thiocarbonyl group of the four-membered ring. However, the minor product reacted with DMC at the thiocarbonyl group to afford a dimethoxythiirane. A product from a corresponding reaction at the carbonyl group could not be found. A rationale for the apparent reversal of relative reactivities of the carbonyl and thiocarbonyl groups is offered, with supporting
    由2,5-二氢-1,3,4-恶二唑与2,2,4,4-四甲基-3-硫代氧代环丁酮热解而生成的二甲氧基卡宾(DMC)反应,主要得到2,2-二甲氧基-3, 3,5,5-四甲基-4-硫代氧杂环戊酮可通过整体插入C-CO键而扩环。从整体插入C-CS键起的4,4-二甲氧基-2,2,5,5-四甲基-3-硫代氧杂环戊酮是次要产物。因此,卡宾优先在羰基而非四元环的硫代羰基上反应。但是,次要产物在硫羰基上与DMC反应,得到二甲氧基硫代硅烷。找不到相应的羰基反应产物。提供了明显逆转羰基和硫代羰基的相对反应性的理由,并提供了支持证据。
