  sterochemistry of the addition across the alkene are best understood with a phenonium ion structure for the adduct. The nucleophile entering in beta can be varied under conditions in which the adduct cation is trapped more efficiently than the starting phenyl cation. Thus, beta-methoxyalkylanilines are formed when the irradiation is carried out in methanol. beta-Iodoalkylanilines are obtained in acetonitrile

  在极性溶剂中辐照4-氯苯胺或其N，N-二甲基衍生物会生成相应的三线态苯基阳离子。这些被烯烃捕获，以中等至良好的产率产生芳基化产物。B3LYP计算表明，三线态阳离子以可忽略不计的活化能滑动到与乙烯的键合加合物上，而与水仅形成略微稳定的CT复合物（被选为代表性的sigma亲核试剂）。最终产物的结构取决于加合物阳离子与烯烃的优选路径。在芳基烯烃的情况下，它去质子化为二苯乙烯衍生物，而从2，3-二甲基-2-丁烯和烯丙基三甲基硅烷，通过消除γ中的电离基团获得烯丙基苯胺。在单和二取代的烯烃的情况下，阳离子加氯而不是消除氯，得到β-氯烷基苯胺。通过加合物的phen离子结构可以最好地理解整个烯烃的加成反应的区域和立体化学。在其中加合物阳离子比起始苯基阳离子更有效地被捕获的条件下，可以改变进入β的亲核试剂。因此，当在甲醇中进行照射时，形成β-甲氧基烷基苯胺。在含碘化物和未取代的烷基苯胺的乙腈中，在硼氢化钠的

• Smooth Synthesis of Aryl- and Alkylanilines by Photoheterolysis of Haloanilines in the Presence of Aromatics and Alkenes

  [GRAPHICS]Irradiation of 4 chloro-N,N-dimethylaniline in acetonitrile in the presence of benzene and of various alkenes leads to heterolytic dehalogenation and trapping of the cation. 4-(Dimethylamino)biphenyl is formed in the first case, while with alkenes beta-chloroalkylanilines, stilbenes, or allylanilines are obtained depending on the alkene structure. 4-Fluoroaniline is similarly dehalogenated.

• Catalytic photocarboxylation of 1,1-diphenylethylene with N,N,N′,N′-tetramethylbenzidine and carbon dioxide

  日期：2007.4

  Photocarboxylation of 1,1 -diphenylethylene with N,N,N',N',-tetramethylbenzidine (TMB) in MeCN under bubbling Of CO2 proceeded with high catalytic efficiency, giving 3,3-diphenylacrylic acid (DPA) and 3-hydroxy-3,3-diphenylpropionic acid (20). The turnover number (TON=(DPA+20)/TMB) reached 17. Similarly, 1-phenyl-1-cyclohexene yielded cis-2-acetamido-2-phenylcyclohexanecarboxylic acid with TON 5.9. As compared with related N,N-dimethylaniline derivatives, TMB is more resistant to photodecomposition, has the much larger absorbance in the S-0 -> S-1 transition, and has the lower quenching efficiency by CO2. Probably these factors are partly responsible for the high TON observed for TMB. (c) 2007 Elsevier Ltd. All rights reserved.
