  低温氩基质中取代氧杂环丙烷的光化学形成和反应性

  摘要：

  Diphenyl oxathiirane, formed by irradiation of thiobenzophenone S-oxide at 77 K, is photochemically converted into a blue, thermally unstable compound which decomposes at ca 100–110 K (λmax 550 nm, (ϵ ca 11,000). Lack of change in magnetic susceptibility during the light induced conversion of sulfine to ketone via the oxathiirane and the subsequent blue intermediate implies the absence of triplet and
