    酸性介质中锇催化烯烃二羟基化:旧工艺,新技巧
    摘要:
    对锇催化的二羟基化中 500 多种不同功能化添加剂的筛选发现,当反应介质的 pH 值保持在酸性时,缺电子烯烃转化为相应二醇的效率更高。进一步的研究已将柠檬酸确定为首选添加剂,因为它可以制备非常纯的二醇,产率通常超过 90%。正如这里所描述的,现在可以成功地对更广泛的烯烃类别进行二羟基化。该过程在实验上很简单,在大多数情况下,只需将反应物溶解在水或水/叔丁醇混合物中,搅拌它们,然后过滤出纯二醇产物。

  • Wittig Reactions in Water Media Employing Stabilized Ylides with Aldehydes. Synthesis of α,β-Unsaturated Esters from Mixing Aldehydes, α-Bromoesters, and Ph<sub>3</sub>P in Aqueous NaHCO<sub>3</sub>

    range of stabilized ylides and aldehydes. Despite sometimes poor solubility of the reactants, good chemical yields normally ranging from 80 to 98% and high E-selectivities (up to 99%) are achieved, and the rate of the reactions in water is unexpectedly accelerated. The efficiency of water as a medium in the Wittig reaction is compared to conventional organic solvents ranging from carbon tetrachloride
    事实证明,水是在多种稳定的乙炔和醛上进行维蒂希反应的有效介质。尽管有时反应物的溶解度较差,但通常可获得80-98 %的良好化学收率和较高的E选择性(高达99%),并且在水中的反应速度出乎意料地加快了。将水作为Wittig反应介质的效率与常规有机溶剂(从四氯化碳到甲醇)进行了比较。当存在大量疏水性实体(例如芳香族,杂环芳香族甲醛和长链脂族醛与三苯基膦)时,维蒂希水溶液反应最有效。该Ë / ž维蒂希产物的β-异构体比例取决于电子接受/给体能力和存在于芳环中的取代基的位置。研究了添加剂(例如苯甲酸,LiCl和十二烷基硫酸钠(SDS))对Wittig反应的影响。Wittig反应也可以在酸性实体例如苯酚和羧酸的存在下进行。另外,脂族醛中的大α-取代基不会危害反应。还证明了醛的水合物可以直接在含水维蒂希反应中用作底物。Wittig水溶液的反应范围扩展到Ph 3的一锅混合物的24个例子碳酸氢钠溶液中的P

    Water is demonstrated to be an excellent medium for the Wittig reaction employing stabilized ylides and aldehydes. Although the solubility in water appears to be an unimportant characteristic in achieving good chemical yields and E/Z-ratios, the rate of Wittig reactions in water is unexpectedly accelerated.
    事实证明,水是采用稳定化的丙烯化物和醛类进行维蒂希反应的极佳介质。尽管在水中的溶解度对于获得良好的化学收率和E / Z-比值似乎不是重要的特征,但是水中的维蒂希反应速率却出乎意料地加快了。

  • Pd-Catalyzed Sequential C–C Bond Formation and Cleavage: Evidence for an Unexpected Generation of Arylpalladium(II) Species
    作者:So Won Youn、Byung Seok Kim、Arun R. Jagdale
    DOI:10.1021/ja304616q
    日期:2012.7.18
    A Pd(II)-catalyzed reaction engaging alkenyl beta-keto esters is reported that leads to the formation of 1-naphthols and an unexpected generation of arylpalladium-(II) species. Interception of the in situ generated arylpalladium(II) species in a Mizoroki-Heck reaction, together with additional mechanistic studies, provided strong evidence in support of the first aromatization-driven beta-carbon elimination process. A single Pd catalyst served to promote a series of both C-C bond forming and cleavage events in an unprecedented manner.
