the potential products include π-alkyne, hydridoalkynyl, and vinylidene complexes, depending on the metals and the ligand environment. The reaction mechanism typically involves an initial step where the alkyne molecule binds to the metal center in an η2 configuration. The complex can then undergo tautomeric rearrangements to produce hydride alkynyl (C−H oxidative addition) and/or vinylidene (1,3-hydrogen shift/l,2- hydrogen shift) derivatives. From the energetic point of view, it is generally accepted that the π-alkyne and vinylidene forms represent the kinetic and thermodynamic products, respec- tively, with the hydridoalkynyl form as an intermediate species. |

the potential products include π-alkyne, hydrido alkyny, and vinylidene complexes, depending on the metals and the ligandenvironment. 蛋白产品例如π-炔属烃,氢化炔基,以及亚乙烯基配合物，都依赖于金属和配位环境。 The reaction mechanism typically involves an initial step where the alkyne molecule binds to the metal center in an η2 configuration. 反应机理通常涉及一个厨师步骤，这个步骤中，炔分子都以η2的结构绑定到金属分子中心。 The complex can then undergo tautomeric rearrangements to produce hydride alkynyl (C−Hoxidative addition) and/or vinylidene (1,3-hydrogen shift/l,2- hydrogen shift) derivatives. 该复合物会经历互变异构的重排，从而生成氢化炔基（碳-氧化应激添加）以及/或者亚乙烯基派生物 From the energetic point of view, it is generally accepted that the π-alkyne and vinylidene forms represent the kinetic and thermodynamic products, respectively, with the hydridoalkynyl form as an intermediate species. 从能量活跃的观点来看，普遍接受的观点是，π-炔属烃和亚乙烯基形式能呈现出活跃的热力学产品，与此对应，氢化炔基形式是一种中间物质。 |
