Abstract:
The first metallacomplex containing both 1,3-bis(diphenylphosphino)propane and silsesquoxane ligands is presented, which adopts an intriguing three-component ionic structure. According to X-ray diffraction studies, the central dianionic CuII12-methylsilsesquioxane cage is balanced by two external cationic [CuI(dppp)2] species, giving a total Cu14 nuclearity. The cage component of the complex encapsulates hydroxyl, carbonate, and chloride species. The complex was evaluated as a catalyst for the effective oxidation of alkanes to alkyl hydroperoxides and of alcohols to ketones using peroxides.

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...
Alkynes to Aldehydes and Ketones: Hydroboration-Oxidation
One of the convenient methods for the preparation of aldehydes and ketones is via hydration of alkynes. Hydroboration-oxidation of alkynes is an indirect hydration reaction in which an alkyne is treated with borane followed by oxidation with alkaline peroxide to form an enol that rapidly converts into an aldehyde or a ketone. Terminal alkynes form aldehydes, whereas internal alkynes give ketones as the final product.
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.
