  N-杂环卡宾/羧酸共催化能够在低催化剂负载下对要求苛刻的醛/烯醛进行氧化酯化

  摘要：

  我们报告发现简单的羧酸，如苯甲酸，可以提高 N-杂环卡宾 (NHC) 催化剂在醛的氧化酯化中的活性。一种简单有效的转化各种位阻α-和β-取代脂肪醛/烯醛的简单有效方案，由一种新型且易于获得的N-Mes-/N-2,4,6-三氯苯基1,2催化,4-三唑鎓盐和苯甲酸作为助催化剂被开发出来。一系列迄今为止不适合 NHC 催化酯化的 α/β-取代的脂肪族醛/烯醛可以在 0.02-1.0 mol% 的典型催化剂负载下反应。对于苯甲醛，即使是 0.005 mol% 的 NHC 催化剂也证明是足够的：NHC 催化中达到的最低值。

• A microwave-assisted highly practical chemoselective esterification and amidation of carboxylic acids
  作者：Gunindra Pathak、Diparjun Das、Samuel Lalthazuala Rokhum

  DOI：10.1039/c6ra22558f

  日期：——

  The ubiquitousness of esters and amide functionalities makes their coupling reaction one of the most sought-after organic transformations. Herein, we have described an efficient microwave-assisted synthesis of esters and amides. Soluble triphenylphosphine, in conjugation with molecular iodine, gave the desired products without the requirement for a base/catalyst. In addition, a solid-phase synthetic

  酯和酰胺官能团无处不在，使它们的偶联反应成为最受欢迎的有机转化之一。在此，我们已经描述了酯和酰胺的有效微波辅助合成。可溶性三苯基膦与分子碘结合，可得到所需的产物，而无需碱/催化剂。另外，为所述转化引入了固相合成路线，其与溶液相路线相比具有更多的优点，例如低湿度敏感性，易于处理，通过简单过滤分离产物和可重复使用性。简而言之，我们的方法本质上是简单，温和，绿色和高度化学选择性的。
