  寡乙二醇作为亲核取代反应的高效多功能启动子。

  摘要：

  在此，我们报告了n低聚乙二醇（oligoEGs）作为使用碱金属盐进行亲核取代反应的多官能促进剂。在测试的各种oligoEG中，五甘醇（pentaEG）具有最有效的催化活性。特别地，当与所检查的其他亲核试剂相比时，由pentaEG启动子显着活化由CsF产生的氟亲核试剂。在pentaEG启动子存在的情况下，我们还进行了各种简便的亲核取代反应，例如卤化钾，乙酸盐，硫代乙酸盐，氰化物和叠氮化钠分别对各种底物进行卤化，乙酰氧基化，硫代乙酰氧基化，硝化和叠氮化。所有这些反应以优异的产率提供了它们所需的产物。此外，pentaEG和tert的组合酒精介质在碱性敏感底物与碱性亲核试剂（分别为氟化铯和甲醇钾）的亲核取代反应（氟化和甲氧基化）中显示出巨大的效率。oligoEGs的催化作用已通过量子化学方法进行了研究。发现oligoEGs中的氧原子充当金属阳离子上的Lewis碱，以产生“柔性”亲核试剂，而两个末端

  A facile one-pot synthetic method of building aryloxyalkyl esters was developed using various types of phenolic esters with halogenated alcohols. The ready availability of both starting materials, coupled with the required simple experimental technique, enables the current synthetic method of producing aryloxyalkyl esters in a fast and efficient way. It is noteworthy that acyl transfer was demonstrated

  Oligoethylene glycol substituted imidazolium salts were synthesized as promoters for a range of SN2 reactions, and their efficiency was examined. These tailor-made organic promoters enhanced the nucleophilicity of alkali metal salts significantly through the combined effects of two promoters (oligoethylene glycols and imidazolium salts) in a single molecule. The effects of the oligoethylene glycol

  Achiral polyether derivatives have been shown to dramatically accelerate SN2 reactions by the simultaneous activation of both the nucleophile (KF) and electrophile (sulfonate; see picture). By using chiral variants as catalysts, the desilylative kinetic resolution of the silyl ethers of racemic secondary alcohols has been achieved. Density functional calculations provide detailed insight into the modes

• Polymer-supported oligoethylene glycols as heterogeneous multifunctional catalysts for nucleophilic substitution

  We investigated various structurally modified polystyrene-supported oligoethylene glycols (PSoligoEG) in order to find an optimized PSoligoEG by examining the dependence of their catalytic activity on the oligoethylene glycol chain length and the loading level of the oligoethylene glycol portion on the polystyrene support. From this, we found that the PSpentaEG with the highest pentaEG loading had the best catalytic efficacy among the various PSoligoEGs in nucleophilic substitutions. This PSpentaEG absorbed both polar aprotic solvents, such as DMSO, DMF, and acetonitrile, as well as protic media, such as tert-amyl alcohol and aqueous acetone, and swelled considerably. To expand the scope of the PSpentaEG as a heterogeneous catalyst for diverse nucleophilic displacement reactions, we carried out the thioacetoxylation, nitrilation, azidation, iodination, bromination, chlorination, and methoxylation using the corresponding alkali metal salts in the presence of PSpentaEG in various solvents; all the reactions proceeded smoothly, affording the corresponding products in high yields.
