  • HYDROSILYLATION PROCESS CATALYSED BY A MANGANESE COMPLEX
    Publication number: 20260217739
    Abstract: The present invention relates to hydrosilylation reactions between a monosubstituted alkene compound and a compound comprising at least one hydrogen atom bonded to a silicon atom. More specifically, the invention relates to a process for hydrosilylation of an unsaturated compound A comprising at least one monosubstituted alkene function with a compound B comprising at least one hydrosilyl function, catalysed by a manganese complex C having the oxidation state I, in the presence of air and/or water. This hydrosilylation reaction between an alkene compound and a compound comprising at least one hydrogen atom bonded to a silicon atom makes it possible in particular to crosslink silicone compositions.

  • HYDROSILYLATION METHOD CATALYSED BY AN IRON COMPLEX
    Publication number: 20240287255
    Abstract: The present invention relates to a method for hydrosilylation of an unsaturated compound comprising at least one alkene function or one alkyne function with a compound comprising at least one hydrosilane function, said method being catalysed by an iron complex represented by the formula Fe[Si(SiR3)3]2 Ln, wherein each R is a hydrogen atom or a hydrocarbon group having 1 to 30 carbon atoms, optionally substituted by one or more halogen atoms, each L is an ether ligand, and n=1, 2 or 3. The present invention also relates to a method for preparing said iron complex, as well as to the use thereof as a catalyst for the hydrosilylation of an alkene or alkyne.
