  Methylbenzene cation radical .alpha.-fragmentation selectivities revealed in SET-photoadditions of p-xylene derivatives to 1,4-dicyanonaphthalene [SET = single electron transfer]

  摘要：

  SET-promoted photoreactions of selected p-xylene derivatives, including p-xylene (3a), p-phenylenediacetic acid (3b), p-bis[(trimethylsilyl)methyl]benzene (3c), p-[(trim ethylsilyl)methyl]toluene (3d), p-tolylacetic acid (3e), and p-[(trimethylsilyl)methyl]phenylacetic acid (3f), to 1,4-dicyanonaphthalene have been investigated. These processes lead to clean and selective formation of 1:1 adducts whose nature is controlled by alpha-heterolytic fragmentation reactions occurring at benzylic positions of arene cation radicals which serve as key reactive intermediates. The results indicate that the relative rates of cation radical fragmentations of the type ([ArCH2E].+ + B: --> ArCH2.+ BE) depend on the nature of the electrofugal group, E, in the following order: E = SiMe3 > CO2H > H. The experimental basis for these conclusions is discussed.

  germane, and stannane in polar solvents gave the arylmethylated products of DCN in high yields. The fluorescence of DCN was efficiently quenched both in polar and nonpolar solvents by these group 14 organometallic compounds. In cyclohexane, the emission from the exciplex between DCN and arylmethylsilanes was observed. The mechanistic features of the photoreaction are described.

  oxygenation of the arylmethyl organometallic compounds occurred in the photoreaction under oxygen atmosphere. Key intermediates in these reactions in acetonitrile were radical ions which were generated via photoinduced electron transfer from the arylmethyl organometallic compounds to the excited singlet of DCN or DCA. The cleavage of the carbon–metal bond of the radical cations of the arylmethyl compounds

  在各种条件下研究了芳基甲基硅烷、-锗烷和-锡烷与 1,4-二氰基萘 (DCN) 和 9,10-二氰基蒽 (DCA) 的光反应。DCN和DCA的芳甲基化发生在氮气气氛下的光反应中，而芳甲基有机金属化合物的氧化发生在氧气气氛下的光反应中。乙腈中这些反应的关键中间体是自由基离子，它们是通过光诱导电子从芳甲基有机金属化合物转移到 DCN 或 DCA 的激发单线态而产生的。芳甲基化合物自由基阳离子的碳-金属键断裂导致芳甲基自由基的形成。然后自由基与 DCN 和 DCA 的自由基阴离子反应生成芳甲基化化合物或与氧反应生成含氧化合物。光反应的效率受溶剂和添加到反应系统中的材料的影响。在光反应...
