    coordination chemistry. In this paper, we propose the convenient synthesis of NHC–nickel compounds. The 9-nickelafluorenyllithium complex reacts with imidazolium or imidazolinium salts to afford 9-nickelafluorenyl–NHC salts via ionic metathesis with very good yields (66–92%). These compounds can be isomerised at elevated temperatures to give Ni–NHC complexes with excellent yields (88–91%), probably
    卡宾配合物的性质研究是现代配位化学最重要的领域之一。在本文中,我们提出了NHC-化合物的方便合成方法。9-络合物与咪唑鎓或咪唑啉鎓盐反应,通过离子复分解反应获得9-基-NHC盐,收率非常好(66-92%)。这些化合物可以在高温下异构化,从而可能通过介导的氢转移至联苯部分,从而以优异的产率(88-91%)得到Ni-NHC复合物。在该反应中,环环本身在卡宾前体的去质子化中用作碱。DFT计算显示出合成盐的热力学不稳定性,吉布斯自由能差为1 -84千焦耳摩尔-1在298K和-167千焦摩尔-1在374 K.将所得到的盐和碳烯配合物在固体状态下相对空气和湿气是稳定的。

    Water-soluble gold(I) N-heterocyclic carbene complexes were synthesized and characterized using X-ray absorption spectroscopy (XAFS) in combination with traditional analytical techniques such as NMR, mass spectrometry, and UV–vis spectroscopy. XANES and EXAFS regions are sensitive to coordination number, ligand electronic structure, and distance around the metal center, providing information on the
