Abstract:
A heterometallic magnesium-aluminium hydride complex is reported for the selective homologation of C1 building blocks (CO and CNXyl, Xyl = 2,6-Me2C6H3) to form products containing C2 and C3 chains. CO reacts to form known deltate or ethynediolate motifs with different outcomes depending on the steric demands of the ligand on magnesium. In contrast, CNXyl reacts through a combination of carbon-carbon bond formation and hydride migration to form a novel metalated ethene diamidolate ligand [RN1C1C2(H)N2R]3-.

Reduction of Alkynes to cis-Alkenes: Catalytic Hydrogenation
Like alkenes, alkynes can be reduced to alkanes in the presence of transition metal catalysts such as Pt, Pd, or Ni. The reaction involves two sequential syn additions of hydrogen via a cis-alkene intermediate.

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...
Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can...
