摘要/Abstract

碱土金属及其化合物由于其储量丰富、成本低而被应用于催化反应中.近年来，碱土金属催化脱氢偶联反应、硼氢化反应、氢膦化反应、氢胺化反应以及氢化硅烷化反应等被关注和研究，无论在实验还是原理上都取得了大量的进展.针对这类反应及其机理进行总结归纳，从而完整描绘了碱土金属在氢化或脱氢反应中起到的作用.这类反应中，往往都涉及到碱土金属氢化物作为活性物种，反应过程中都要经历碱土金属氢共价键的形成和断裂.通过对这些反应的分类和讨论，从整体上认识了这类反应的反应条件和反应历程，为今后设计碱土金属催化剂和同类型反应的催化循环提供了指导.

Alkaline-earth-metal compounds have been widely concerned due to its abundant reserve and the low-cost. In recent years, alkaline-earth-metal catalysis has achieved great progress in dehydrocoupling, hydroboration, hydrophosphination, hydroamination, hydrosilylation reactions experimentally and therotically. These types of reaction and catalytic mechanism, leading to indentify the role of alkaline-earth-metal in hydrogenation and dehydrogenation reaction are summarized. These reactions, in which the metal-hydride act as active species, generally undergo the reaction pathway involving the cleavage and formation of the metal-hydride covalent bond. The reaction features and mechanisms are generally recognized accrossing to the classification and discussion of these reactions, which would provide guidance for further development of alkaline-earth-metal catalysis.
Key words: alkaline-earth-metals catalyst, hydrofunctionalization reaction, mechanism study, recent advance
