The invention discloses an SBA-15-supported 2-azaadamantane nitroxide radical catalyst and its preparation and application. SBA-15 and 1-methyl-2-azaadamantyl- 4-(phenyl) methanol is a raw material, 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide is used as a condensing agent, 4-dimethylaminopyridine is used as a catalyst, and the mixture is prepared in dichloromethane. Condensation reaction is carried out in a solvent, filtered, washed, and vacuum-dried to obtain grafted SBA-15; in tetrahydrofuran solvent, the grafted SBA-15 is oxidized with m-chloroperoxybenzoic acid at room temperature under nitrogen protection, filtered, Wash and dry to obtain SBA-15 immobilized 2-azaadamantane-nitroxide radical catalyst. SBA-15 supported 2-azaadamantane-nitroxide radical catalyst can be used for the oxidation of alcohols. |
