  catalysis has been emerged as a powerful strategy to promote organic transformations that cannot be achieved by each individual independently. Herein, a new protocol for the synthesis of primary amides from olefins, CO and NH3 through one-pot tandem methoxycarbonylation-aminolys was presented over a bi-functional ligand (L1) based rhodium catalyst with functions of co-catalysis. L1 is composed of the phosphino-fragment

  过渡金属催化与有机催化以协同催化，协同催化或/和顺序催化的方式相结合已成为一种强有力的策略，可以促进每个人无法独立实现的有机转化。在此，在具有共催化功能的基于双功能配体（L1）的铑催化剂上，提出了一种通过一锅串连的甲氧基羰基化-氨基分解物从烯烃，CO和NH 3合成伯酰胺的新方案。L1由膦片段和氨基/亚氨基互变异构部分组成。然后L1的Rh催化体系证明了Rh-P过渡金属催化和互变异构催化的结合。在这种串联的甲氧基羰基化-氨解反应中，NH 3还用作配体，与膦酸酯片段协同作用，共同修饰负责烯烃第一步甲氧基羰基化以生成酯的Rh催化剂的性能，并且Rh-tailed互变异构体催化剂负责随后的氨解反应以生成目标伯酰胺。

• Synthesis of hindered functionalized ethers via high-pressure addition of alcohols to acrylic compounds
  作者：Gérard Jenner

  日期：2001.7

  or β-Substituted acrylic compounds react sluggishly or not at all. In this case, high-pressure activation can remove steric inhibition leading to good yields of the corresponding ethers. Reactions involving crotonic compounds (hindered β reaction center) show higher pressure dependence than the corresponding additions of alcohols to methacrylic analogs (free β reaction center). This is in agreement

  从合成的观点出发，研究了膦在活化烯烃上的膦催化的1,4-加成反应。α-或β-取代的丙烯酸化合物反应缓慢或根本不反应。在这种情况下，高压活化可以消除空间位阻，从而导致相应醚的良好收率。涉及巴豆化合物（受阻的β反应中心）的反应显示出比依赖的醇更高的压力依赖性，这与将醇相应地添加到甲基丙烯酸类似物（游离的β反应中心）有关。这与空间要求苛刻的反应显示出对压力的敏感性增强的概念是一致的。显然，该结果具有较高的合成价值，因为压力可能能够消除空间抑制作用。
