Homogeneous catalysis with polyhydride complexes

Autor: Juan C. Babón, Miguel A. Esteruelas, Ana M. López

Publikováno v: Chemical Society reviews. 51(23)

Roles of the hydrogen atoms attached to the metal center of transition metal polyhydride complexes, LnMHx (x ≥ 3), are analyzed for about forty types of organic reactions catalyzed by such class of species. Reactions involve nearly every main organ
