During the past 10 years there have been significant advances in Pd(II)-catalyzed oxidation reactions where the use of ligands has led to the development of catalytic systems capable of achieving high turnover numbers, which employ molecular oxygen as the sole stoichiometric oxidant. This Feature article will highlight some of the recent developments in direct molecular oxygen-coupled Pd(II)-catalyzed oxidation reactions with an emphasis on enhanced catalytic systems and new reactions. Additionally, limitations of current catalytic systems, such as ligand oxidation, are presented and their implications for the development of new reactions are discussed.
在过去十年中,钯(II)催化的氧化反应取得了重大进展,其中配体的使用促使了能够实现高周转数的催化体系的发展,这些体系以分子氧作为唯一的化学计量氧化剂。这篇专题文章将重点介绍直接分子氧偶联钯(II)催化氧化反应的一些最新进展,着重于增强的催化体系和新反应。此外,还介绍了当前催化体系的局限性,如配体氧化,并讨论了它们对新反应开发的影响。
