SOL GEL FUNCTIONALIZED SILICATE CATALYST AND SCAVENGER
This invention relates to materials suitable as metal scavengers and catalysts. The materials are prepared by functionalizing silicate materials such as silica or SBA-15 with a thiol or amine, or other functionalizing agent, in a sol gel process. In a preferred embodiment, the metal is palladium and...

| description | This invention relates to materials suitable as metal scavengers and catalysts. The materials are prepared by functionalizing silicate materials such as silica or SBA-15 with a thiol or amine, or other functionalizing agent, in a sol gel process. In a preferred embodiment, the metal is palladium and the functionalizing agent is a thiol. The material may be used as a catalyst for the Suzuki-Miyaura and Mizoroki-Heck coupling reactions. The catalyst materials have extremely low metal leaching, are very stable, and are completely recyclable. |
