Abstract:
A novel triangulo complex was generated by heating, in vacuo, a racemic C2-symmetric octahedral nickel(II) diamine complex. The trinuclear species was identified by single-crystal X-ray diffraction, which revealed a 2:1 ligand stereochemistry relationship in each unit. This solid-state structure evidences the hypothesis that a 1:2 stereochemical relationship lies at the heart of the strong positive nonlinear effect observed in enecarbamate aldol-like reactions catalyzed by nickel(II) diamine complexes.

Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...

Reduction of Alkenes: Catalytic Hydrogenation
Metals like palladium, platinum, and nickel are commonly used in their solid forms — fine powder on an inert surface. As these catalysts remain insoluble in the reaction mixture, they are referred to as heterogeneous catalysts.
The hydrogenation process takes place on the surface of...
