Metal carbyne (M≡C) complexes have been discovered for nearly half a century, however, they gained far less study in comparison with metal-carbon single bond (M—C) and metal carbene (M=C) species in synthetic chemistry. Up to three sigma bonds are possibly forged on a single carbon through metal carbynes or carbyne equivalents, which holds great potentials in organic synthesis but also requires high efficiency of bond formation and precise control of reactivity and selectivity. Along this line, two systems based on stoichiometric transformations of manganese carbynes and ruthenium/rhodium-catalyzed reactions of diazo hypervalent iodine reagents, carbyne equivalents, have emerged recently, which will be highlighted herein. Future potentials and challenges in this intriguing area are also briefly discussed.

通过金属卡宾或卡宾等价物在一个碳上形成三个单键

金属卡宾 (M≡C) 配合物已被发现近半个世纪，但与合成化学中的金属碳单键 (MC) 和金属卡宾 (M=C) 物种相比，它们获得的研究要少得多。通过金属卡宾或卡宾等价物可能在单个碳上形成多达三个 sigma 键，这在有机合成中具有巨大潜力，但也需要高效率的键形成以及对反应性和选择性的精确控制。沿着这条路线，最近出现了两个基于锰卡宾的化学计量转化和钌/铑催化重氮高价碘试剂卡宾等价物反应的系统，将在本文中重点介绍。还简要讨论了这个有趣领域的未来潜力和挑战。
