    Spectroscopic Studies on Photochemical Formation of o-Xylylene in Solution
    摘要:
    The photochemical formation of o-xylylene is studied by two-pulse fluorescence and transient absorption spectroscopy. o-Xylylene is produced by photolysis of alpha,alpha'-dichloro-o-xylene, alpha,alpha'-dibromo-o-xylene, alpha,alpha'-bis(trimethylstannyl)-o-xylene, and 2-indanone at 266 nm in room-temperature cyclohexane solution. On excitation at 308 nm, the fluorescence of o-xylylene is observed with a maximum at 460 nm and a lifetime of 9.3 +/- 0.5 ns. The absorption of o-xylylene is obtained with a maximum at 370 nm. The formation of o-xylylene from alpha,alpha'-dichloro-o-xylene occurs, by 266-nm two-photon excitation, with an apparent yield of 0.30 +/- 0.08 at a fluence of 40 mi cm(-2). Its formation from 2-indanone proceeds, by 266-nm one-photon excitation, with a rate of (1.4 +/- 0.1) x 10(7) s(-1) and a yield of 0.90 +/- 0.08.

    Proximity as origin of unusual photoreactivity is being explored: In the naphtho/ene 5 (X-ray analysis), direct or sensitized photoexcitation induce an efficient meta-addition to the naphthalene nucleus; ortho-(2,3)-addition is not enforced. Naphtho/benzo cyclophane 10, however, is photochemically “inert”. Structurally related benzo/enes 4 and 17 undergo photoequilibration (2:1) with the respective

    electrochemical generation and characterisation of a variety of o-quinodimethanes (o-QDMs) are described together with the outcome of preparative experiments in which they are key intermediates. The quinodimethanes are conveniently formed, in DMF, by both direct and redox-catalysed electroreduction of 1,2-bis(halomethyl)arenes. Their predominant reaction is polymerisation to poly(o-xylylene) (o-PX) polymers
    描述了各种邻喹啉甲烷(o- QDMs)的电化学生成和表征,以及以它们为关键中间体的制备实验的结果。这醌二甲烷在DMF中,通过直接和氧化还原催化的1,2-双(卤甲基)芳烃的电还原可方便地形成芳烃。他们的主要反应是聚合反应到聚(邻二甲苯)(o -PX)聚合物。在存在亲双烯体的情况下,电生成的o- QDM可以进行有效的环加成反应,并且已经基于伏安法,制备和立体化学实验尝试了可能机制之间的区别。与相应甲酯的先例相反,马来酸二苯酯自由基-阴离子仅缓慢地异构化为富马酸酯自由基-阴离子,但会共电解2,3-双(溴甲基)-1,4-二甲氧基苯 和 马来酸二苯酯 或者 富马酸二苯酯仅给出相应的反式加合物。共电解马来酸二甲酯 与任一 1,2-双(溴甲基)苯 (更容易减少)或 2,3-双(溴甲基)-1,4-二甲氧基苯(不太容易还原的),得到仅Ô -PX聚合物。根据双亲核取代机制对结果进行了合理化,其中电子转移在亲二

    Coarctate reactions are defined as reactions that include atoms at which two bonds are made and two bonds are broken simultaneously. In the pursuit of the discovery of new coarctate reactions we investigate the fragmentation reactions of cyclic ketals. Three ketals with different ring sizes derived from indan-2-one were decomposed by photolysis and pyrolysis. Particularly clean is the photolysis of
    Coarctate 反应被定义为包括两个键形成和两个键同时断裂的原子的反应。为了发现新的缩氨酸反应,我们研究了环状缩酮的裂解反应。来自indan-2-one的三个不同环大小的缩酮通过光解和热解被分解。特别干净的是 indan-2-one ketal 1 的光解,它产生邻醌二甲烷、二氧化碳和乙烯。该机制形式上对应于光化学允许的缩氨酸裂解。五环缩酮的热解产生多种产物。这与辐射时观察到的缩氨酸裂解在热化学上被禁止的事实是一致的,尽管这个排除原则不适用于螯合反应。相比之下,七环缩酮 3 的裂解在热化学上是允许的,而在光化学上是禁止的。在热解 3 时,分离出几种产物,这可以通过缩氨酸裂解来解释。然而,反应不太干净,逐步机制可能会相互竞争。
