  摘要：

  由羧酸和2-氯-4,6-二甲氧基-1,3,5-三嗪反应得到的2-酰氧基-4,6-二甲氧基-1,3,5-三嗪被用作酰化剂，用于从伯醇、仲醇和叔醇合成酯。由于酰化条件温和，该方法可以应用于不稳定的醇与芳香酸和脂肪酸（包括α-支链酸）的良好产率的酯化反应中。

  carboxylic acids, such as benzoic acid, boost the activity of N-heterocyclic carbene (NHC) catalysts in the oxidative esterification of aldehydes. A simple and efficient protocol for the transformation of a wide range of sterically hindered α- and β-substituted aliphatic aldehydes/enals, catalyzed by a novel and readily accessible N-Mes-/N-2,4,6-trichlorophenyl 1,2,4-triazolium salt, and benzoic acid as co-catalyst

  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。

  Disclosed are certain moisture curable prepolymers formed by the reaction of diphenylmethane diisocyanate (MDI) with conventional polyether polyols to produce sealants and coatings exhibiting excellent combinations of physical properties, most notably, high tensile strength, high tear resistance, and high elongation. These combinations of physical properties in the moisture-cured polymer are superior to those obtained from prepolymers of the so-called “low unsaturation” polyether polyols. The moisture curable prepolymers offer improved polymer properties, reduced viscosity, and lower raw materials cost in relation to the prior art prepolymers based on low unsaturation polyether polyols.

  已公开的某些可湿气固化的预聚物是由二苯基甲烷二异氰酸酯（MDI）与传统的聚醚多元醇反应形成的，用于生产密封剂和涂料，具有优异的物理性能组合，特别是高拉伸强度、高抗撕裂性和高伸长率。湿气固化聚合物的这些物理性能组合优于从所谓的 "低不饱和 "聚醚多元醇预聚物中获得的物理性能组合。与现有技术中基于低不饱和聚醚多元醇的预聚物相比，湿气固化预聚物具有更好的聚合物特性、更低的粘度和更低的原材料成本。
