Recent Advances in Alkaline-Earth-Metal-Catalyzed Hydrofunctionalization Reactions

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.
