Since the discovery of the first air stable NHC, this class of compounds has been intensively studied and applied in organometallic chemistry and homogeneous catalysis due to the stability brought to the metal centre. Alternatively, phosphorus based family ligands have already a very long history in these fields of chemistry. It was naturally obvious that the NHC and the phosphorus ligands had to be mixed for the best of organometallic chemistry and homogeneous catalysis. This perspective will highlight the new synthetic routes for NHC bearing a phosphorus moiety such as NHC-phosphenium salt, N-phosphorylated-imidazolium salt, 4-phosphino or 4,5-diphosphino-imidazolium salt and tethered phosphino-imidazolium salt. Then, the recent applications in organometallic chemistry and homogeneous catalysis will be presented.
自从发现第一个空气稳定的 NHC 以来，由于其为金属中心带来的稳定性，这类化合物在有机金属化学和均相催化领域得到了深入的研究和应用。另一方面，磷基配体在这些化学领域已经有很长的历史。很显然，NHC 和磷配体必须混合使用，才能达到有机金属化学和均相催化的最佳效果。本综述将重点介绍含有磷部分的 NHC 的新合成路线，如 NHC-膦盐、N-膦酰化咪唑盐、4-膦基或 4,5-二膦基咪唑盐和桥联膦基咪唑盐。然后，将介绍它们在有机金属化学和均相催化中的最新应用。
