• The photochemical reactivity of some benzoylthiophenes. IV. The effect of an adjacent methyl group on the excited state reactivity of 3-benzoylthiophene
  作者：D. R. Arnold、C. P. Hadjiantoniou

  DOI：10.1139/v78-321

  日期：1978.8.1

  The electronic absorption and phosphorescence emission spectra and the photochemical reactivity of several methyl-3-benzoylthiophenes (2- and 4-methyl-3-benzoylthiophene (1, 2), 2,5-dimethyl-3-benzoylthiophene (3), and 3-(2-methylbenzoyl)thiophene (4)) have been studied. Partial state diagrams have been constructed. The lowest energy absorption in hexane solution in every case is the carbonyl n → π*

  几种甲基-3-苯甲酰噻吩（2-和4-甲基-3-苯甲酰噻吩 (1, 2)、2,5-二甲基-3-苯甲酰噻吩 (3) 和 3）的电子吸收和磷光发射光谱以及光化学反应性-(2-甲基苯甲酰基)噻吩 (4)) 已被研究。部分状态图已经构建。在每种情况下，己烷溶液中的最低能量吸收是羰基 n → π* 转变。这些酮的两个最低三线态在能量上接近，事实上，发射三线态（n,π* 或 π,π*）的性质取决于甲基取代的位置和溶剂。研究的光化学反应包括分子内夺氢（通过在全氘甲醇溶液中辐照后相邻甲基中的氘交换显示），乙炔二甲酸二甲酯光环加成到噻吩环上，异丁烯光环加成到羰基上。概括，可能有助于预测光化学反应...
