目前仅有当量金属与芳烃或1,3-二烯预制成π-Lewis碱性络合物,再与亲电试剂反应的报道,但反应后所生成的复合物需经氧化才能脱除金属得到有机产物,这不仅步骤冗长且基团兼容性差 (Scheme 1c)。 Scheme 1. General Activation Modes of Lewis Acidsand Bases 基于上述背景,四川大学陈应春&杜玮团队和第三军医大学的欧...
这些特性,使得Pd(0)可作为一种新颖高效的π-Lewis碱催化剂促进1-苯基-1,3-丁二烯1a与亚胺2a的反应 (Scheme 2c)。详细的对照实验 (Scheme 2d and 2f)和DFT计算验证了π-Lewis碱催化途径, Pd(0)与1a配位形成η2-配合物Int1,...
Scheme 1. General Activation Modes of Lewis Acids and Bases 基于上述背景,四川大学陈应春&杜玮团队和第三军医大学的欧阳勤教授合作,致力于阐明π-Lewis碱催化的基本理论并利用Pd(0)作为新颖高效的π-Lewis碱催化剂实现系列具有挑战性的不对称反应。该研究团队最近受邀在JACS上撰写该领域的前瞻性综述。

英语化学问题, 急用~~According to the Lewis theory of acids and bases an acid is a proton donor and a base is a proton acceptor. 这句话对不对? 还是应该according to Bronsted Lowry theory ? 急用 谢谢~~ 答案 应该是后一种 According to Bronsted Lowry theory.原因是:布朗特(Bronsted)的酸碱质子...
Lewis Acids and BasesLewis Acids and BasesWe saw in chapter 1 that complex compounds are often formed by direct reaction between a 'simple' molecule or ion and a ligand. How do we know which 'simple' substances will react with ligands? One wadoi...
