  Laser Flash, Laser-Drop, and Lamp Photolysis of 1,3-Dichloro-1,3-diphenylpropane. One- versus Two-Photon Reaction Pathways

  摘要：

  Low intensity irradiation of 1,3-dichloro-1,3-diphenylpropane (1) in cyclohexane leads to the formation of 3-chloro-1,3-diphenylpropyl radical (2) through homolytic C-CI bond cleavage. Radical 2 gives rise to final products typical of free radical reactions. Neither 1,2-diphenylcyclopropanes (6) nor 3-cyclohexyl-1,3-diphenylpropene (20) are obtained under these conditions. Nevertheless, high intensity laser irradiation of the initially formed monoradical 2 leads to the 1,3-diphenylpropenyl radical (3) detected with nanosecond techniques. This intermediate is completely trapped by the cyclohexyl radicals generated in the medium to yield 20. Photolysis of 1 with the laser-drop technique leads to the cyclopropanes 6 as major photoproducts.

  Copper(II) on a 4 Å molecular sieve support catalyses the chemoselective addition of alkyl- and arylmagnesium halides to chalcones. Only the 1,4-addition products were obtained in high yields.

  Copper complexes of phosphoramidites efficiently catalyzed asymmetric addition of arylboron reagents to acyclic enones. Importantly, rare 1,4-insertion of arylcopper(I) was identified which led directly to O-bound copper enolates. The new mechanism is fundamentally different from classical oxidative addition/reductive elimination of organocopper(I) on enones.

  calculations, prompted by the experimental aggregation study, revealed an unexpected reaction mechanism, where the coordinating capabilities of DME stabilize a transition state involving two organozinc moieties, lowering the activation energy of the reaction with respect to that seen for THF, enough to explain the fast and quantitative reactions observed experimentally and the different behaviors of

  如果使用 DME 代替 THF 作为溶剂，则在 LiCl 存在下通过将锌直接插入有机卤化物中制备的芳基卤化锌和烷基卤化锌均以优异的收率与非烯醇化不饱和酮发生共轭加成反应。扩散核磁共振测量表明，在合成过程中使用的实验条件下，该物质经历了相当大的聚集，但在两种溶剂之间没有发现实质性差异。由实验聚集研究推动的密度泛函理论计算揭示了一种意想不到的反应机制，其中 DME 的配位能力稳定了涉及两个有机锌部分的过渡态，相对于 THF，降低了反应的活化能，

  isotopic exchange reactions and trapping of two intermediates, provide clues on the several mechanistic steps of this new reaction. Extended studies revealed that beta-alkyl-substituted alpha,beta-unsaturated aldehydes and aliphatic lithium reagents did not afford good yields of the tandem reaction products, while aromatic lithium reagents gave good results. The aggregation features of the aryllithium

  最近报道了（E）-肉桂醛1a与苯基锂之间的串联反应，得到β-取代的二氢查耳酮。反应混合物的NMR光谱研究以及同位素交换反应和两种中间体的捕集为该新反应的几个机理步骤提供了线索。扩展的研究表明，β-烷基取代的α，β-不饱和醛和脂肪族锂试剂不能提供串联反应产物的良好收率，而芳香族锂试剂则能提供良好的结果。芳基锂试剂的聚集特征和扩展的带电离域作用被认为可促进β-选择性。该方法为合成多种β-烷基取代的二氢查耳酮提供了便利的途径。

  catalytic system has been developed for the 1,4‐addition of arylboronic acids to α,β‐unsaturated carbonyl compounds. With catalyst loadings of 1–2 mol%, a series of 1,4‐adducts from chalcones and cinnamates was obtained in moderate to excellent yields within 5–30 min under a nitrogen atmosphere and microwave irradiation. The 1,4‐addition of arylboronic acids to acrylates is less efficient.
