    通过波形控制电合成克服 Kolbe 耦合的局限性
    摘要:
    科尔贝反应通过电化学脱羧偶联形成碳-碳键。尽管研究了一个多世纪,但由于化学选择性极差且依赖贵金属电极,该反应的应用有限。在这项工作中,我们针对这一长期存在的挑战提出了一个简单的解决方案:将电位波形从经典直流电切换为快速交替极性,使各种官能团兼容,并使反应能够在可持续的碳基电极(无定形碳)上进行。这一突破使得人们能够获得有价值的分子,从有用的非天然氨基酸到有前景的聚合物构建模块,这些分子来自容易获得的羧酸,包括生物质衍生的酸。初步机理研究表明波形在调节电极周围局部 pH 值中的作用以及丙酮作为 Kolbe 反应的非常规反应溶剂的关键作用。

  • Long chain (C22-C50) polyunsaturated hydrocarbons, derivatives, synthesis and uses thereof
    申请人:Archer-Daniels-Midland Company

    公开(公告)日:2009-09-01
    The present invention is directed to unsaturated or derivatized long chain (C22-C50) polyunsaturated hydrocarbons and a method of preparing the long chain hydrocarbons via electrocoupling of C12-C26 fatty acids. It has been found that soapstock is an inexpensive source of starting materials for the present method. The present invention is also directed to compositions comprising the long chain polyunsaturated hydrocarbons, which can be used as reactive diluents and modifiers in latex, epoxy, alkyd and polymer compositions. In another aspect, the present invention is directed to derivitization or ozonolysis of the long chain polyunsaturated hydrocarbons. The present method is also useful for preparing C12-26 alkyl esters and C12-26 carbon chain compounds containing a terminal olefin.
    本发明涉及不饱和或衍生的长链(C22-C50)多不饱和碳氢化合物及通过C12-C26脂肪酸的电偶合制备长链碳氢化合物的方法。已发现皂油是本方法的廉价起始原料来源。本发明还涉及包含长链多不饱和碳氢化合物的组合物,可用作乳胶、环氧树脂、醇酸树脂和聚合物组合物中的反应性稀释剂和改性剂。另一方面,本发明涉及长链多不饱和碳氢化合物的衍生物化或臭氧化。本方法还可用于制备C12-26烷基酯和含有末端烯烃的C12-26碳链化合物。

    Esters (mixed anhydrides) derived from aliphatic or alicyclic carboxylic acids (RCO2H) and thiohydroxamic acids or undergo a thermally or photochemically induced radical chain reaction to give sulphides with loss of carbon dioxide. On irradiation at low-temperature however, the chain reaction is essentially supressed. Under these conditions moderate to good yields of dimers R-R are obtained from primary
    衍生自脂肪族或脂环族羧酸(RCO 2 H)和硫代异羟肟酸的酯(混合酸酐),或经过热或光化学诱导的自由基链反应,生成硫化物,并减少二氧化碳的损失。然而,在低温下照射时,链反应基本上被抑制。在这些条件下,从伯酸获得中等至良好产率的二聚体RR。讨论了这些观察结果的机理和综合意义。

    Fatty acid derived carboxylic acids with double bonds, hydroxy-, amino-, keto-, ester- and epoxy groups are anodically coupled to dimers (Kolbe electrolysis) in 29 to 81% yield and up to a 2.5 mol scale. Problems due to the low conductivity of fatty acid salts were overcome by the use of a how cell with a narrow electrode gap. Fatty acids with branched alkyl chains gave dimers with interesting emulsifying properties. Dimethyl hexadecanedioate, accessible from methyl azelate, could be cyclized and further converted into homomuscone and muscone in a few steps. A commercial mixture of dimeric fatty acids (C-36-dicarboxylic acids) has been coupled to give C-70-diesters.
