  For instance, oxidative palladium(II) catalysis is effective with highly substituted alkenes and cyclic alkenes, which are known to be incompatible with other known catalytic conditions. Most examined reactions progressed smoothly to completion at low temperatures and in short times. These interesting results provide mechanistic insights and utilities for a new paradigm of palladium catalytic cycles

  我们在此报告了氧促进 Pd(II) 催化的通用和温和协议的开发，导致烯基和芳基硼化合物与各种烯烃的选择性交叉偶联。与大多数交叉偶联反应不同，这种新方法即使在没有碱基的情况下也能很好地工作，因此避免了不需要的同源偶联。包括二甲基菲咯啉在内的基于氮的配体增强了反应性，并提供了一种高效的立体选择性方法来克服具有挑战性的底物限制。例如，氧化钯 (II) 催化对于高度取代的烯烃和环烯烃是有效的，已知它们与其他已知的催化条件不相容。大多数检查的反应在低温和短时间内顺利完成。

  aliphatic alcohols (also as solvent) allow to produce useful α,β-unsaturated esters in good to excellent yields at 70 °C. Efficient regioselectivity could be controlled in the presence of N-ligands while the P-ligands had no influence on the conversion of substrates and the chemo/regioselectivity of target products. By involving N-ligand 4,7-dimethyl-1,10-phenanthroline in the catalytic system, α,β-unsaturated
