  烷基二苯基次膦酸盐与 10-甲基吖啶鎓离子的 Arbuzov 反应。膦中间体形成与分解的动力学研究

  摘要：

  烷基二苯基次膦酸盐 (1) 与 10-甲基吖啶碘化物 (2a) 快速反应，得到相应的鏻离子 (3)，其逐渐分解为氧化膦，即预期的 Arbuzov 产物。第一步（形成鏻）和第二步（分解鏻）的速率差异很大，这使我们能够对这两个步骤进行独立的动力学研究，发现第一步服从二级动力学和一级动力学分别针对 1 和 2a。当 1 中的烷基取代基是伯或仲时，第二步根据 SN2 机制进行，其中碘离子作为亲核试剂，或者当取代基是叔时，按照 SN1 机制进行。用活化参数对第一步进行更仔细的检查表明，随着 1 中的取代基变得更大，这一步的过渡态变得更像反应物。第二步，活化参数的调查表明，碳氧键在 3 p ...

• Reactivity of Phosphorus-Centered Radicals Generated during the Photoreaction of Diphenylphosphinous Acid with 10-Methylacridinium Salt
  作者：Shinro Yasui、Kosei Shioji、Atsuyoshi Ohno、Masakuni Yoshihara

  DOI：10.1021/jo00112a034

  日期：1995.4

  Diphenylphosphinous acid (1) reacts with 10-methylacridinium iodide (2a) in aqueous acetonitrile during irradiation by visible light under an argon atmosphere at 20 degrees C to afford diphenylphosphinic acid (3) and 10-methylacridan (4). The effects of the solvent and atmosphere and the effect of added iodide ion (I-) or iodine (I-2) on the product distribution show that the mechanism involves initial single-electron transfer (SET) from 1 to 2a in the photoexcited state, by which cation radical 1(+.) and dihydroacridinyl radical 2(.) are generated. Cation radical 1(+.) undergoes electrophilic reaction with water in the solvent, and the resulting phosphoranyl radical decomposes through SET to iodine atom (I-.) rather than undergoing beta-scission, eventually giving 3. Protonation to 2(.) followed by reduction by I- affords 4. These reaction sequences make up the catalytic I-./I- couple. The results are interpreted on the basis of reported redox potentials.

  The thermal-reaction of isopropyl diphenylphosphinite with 10-methylacridinuim iodide results in the formation of a phosphonium ion through a polar process, whereas the reaction under the irradiation of light affords 10-methylacridan as well as isopropyl diphenylphosphinate through single electron transfer (SET) from the former to the latter.
