- An Easily Accessed Nickel Nanoparticle Catalyst for Alkene Hydrosilylation with Tertiary Silanes
-
The first efficient and non-precious nanoparticle catalyst for alkene hydrosilylation with commercially relevant tertiary silanes has been developed. The nickel nanoparticle catalyst was prepared in situ from a simple nickel alkoxide precatalyst Ni(OtBu)2?x KCl. The catalyst exhibits high activity for anti-Markovnikov hydrosilylation of unactivated terminal alkenes and isomerizing hydrosilylation of internal alkenes. The catalyst can be applied to synthesize a single terminal alkyl silane from a mixture of internal and terminal alkene isomers, and to remotely functionalize an internal alkene derived from a fatty acid.

- Synthesis and characterization of biophilic siliconorganic compounds
-
By biophilic compounds we understand derivatives of sugar or phosphoric acid, starting from mono-, di- or trisilanols with long hydrocarbon chains.Through variation of the lipophilic part (length of the chains, number of the chains) and of the hydrophilic zone (headgroups: OH, OMe, phosphates) the amphiphilic property of our manufactured siliconorganic compounds can be adjusted.With this property, the requirement is given for the formation of vesicles.Beside those diacyloxysilanes already prepared and described by us, new and not yet described siliconorganic compounds could be prepared and characterized.These include the silanols 2a-2c and the methoxy compounds 3a-3c.The silanols 2a-2c should serve as aglyca for the transformation to the silicon sugars.
