合成了一系列Pd-N-杂环卡宾(Pd-NHC)与吡嗪(1)、吡啶(2)和NHC(3)的配合物，并用元素分析和光谱方法进行了表征。此外，通过X-射线衍射法确定了化合物3的分子结构。研究了苯基硼酸与芳基氯的Suzuki-Miyaura反应中，这些配体对催化剂活性和配合物1、2、3性能的影响。最后，我们证明了配合物1非常善于重新形成Kumada-Tamao-Corriu交叉偶联反应。版权所有©2013 John Wiley&Sons，Ltd.
A series of Pd–N-heterocyclic carbene (Pd-NHC) complexes with pyrazine (1) or pyridine (2) and NHC (3) were synthesized and characterized by elemental analysis and spectroscopic methods. In addition, the molecular structure of 3 was determined by X-ray diffraction studies. The effects of these ligands on catalyst activation and the performance of complexes 1, 2, 3 were studied on Suzuki–Miyaura reactions of phenylboronic acid with aryl chlorides. Finally, we demonstrated that complex 1 is very adept at re-forming the Kumada–Tamao–Corriu cross-coupling reaction. Copyright © 2013 John Wiley & Sons, Ltd.
