title: Oxidation of organosilanes with nanoporous copper as a sustainable non-noble-metal catalyst.
abstract: Although many noble-metal catalysts have been used for the oxidation of organosilanes, there has been less success with non-noble-metal catalysts. Here, unsupported nanoporous copper (np-Cu) is used to catalyze the oxidation of organosilanes under mild conditions. It is the first time that this reaction has been achieved with a heterogeneous copper catalyst with high activity and selectivity. Both water and alcohols are used as oxidants and the corresponding organosilanols and organosilyl ethers are obtained in high yield. The possible mechanism was obtained by kinetic studies. The catalyst could be reused at least five times without evident loss of activity. As a novel green catalyst np-Cu should play a unique role in organic synthesis.
