Basic Promotors Impact Thermodynamics and Catalyst Speciation in Homogeneous Carbonyl Hydrogenation

Wenjun Yang et al.

Summary: This study demonstrates that additives in homogeneously catalyzed reactions can indirectly participate in catalysis by adjusting the thermodynamics of key transformations. It suggests that reaction promotors should be considered as an integral component of the reaction medium, capable of improving catalytic performance and reshaping the catalytic transformation thermodynamics.

Structure, reactivity and catalytic properties of manganese-hydride amidate complexes

Yujie Wang et al.

Summary: Research shows that a higher efficiency can be achieved by substituting an N-M' group (M' = alkali metals) for the N-H moiety using a large excess of metal alkoxides (M'OR), but the metal-hydride amidate intermediate has not yet been isolated. Furthermore, it is found that M/NM' bifunctional catalysis is superior to classic M/NH bifunctional catalysis in hydrogenation reactions.

Alkali Metal Alkoxides in Noyori-Type Hydrogenations

Pavel A. Dub

Summary: This minireview discusses the accelerative role of alkali metal alkoxides in two important catalytic processes: hydrogenation of ketones and esters with Noyori-type molecular catalysts. The author offers their perspective on the unique mechanistic aspects of these reactions, a subject that remains controversial and often misunderstood.
