Paragraph 0071; 0073; 0075-0079, (2021/06/09)
The invention discloses a zirconium-based MOF catalyst loaded with double active sites as well as a preparation method and an application of the zirconium-based MOF catalyst. The method comprises thefollowing steps: adding zirconium salt and an organic ligand into an organic solvent, taking organic acid as a regulator, and carrying out self-assembly reaction to obtain a metal organic framework; adding salicylaldehyde for aldehyde amine condensation to obtain chelating coordination sites, adding palladium salt, and performing coordination through an impregnation method; reducing the obtained MOF in hydrogen to obtain an MOF loaded with Pd nanoparticles; reacting MOF and zinc salt in an organic solvent, and obtaining the catalyst. The Pd-Zn-coated UiO-68-NH2-CH3 catalyst synthesized by thepreparation method disclosed by the invention has efficient catalytic activity in a tandem alcohol oxidation/aldehyde cyanosilylation reaction. According to the catalyst, a metal organic framework UiO-68-NH2-CH3 is constructed, Pd nanoparticles and Zn are loaded by taking the metal organic framework UiO-68-NH2-CH3 as a carrier, the loading capacity of the Pd nanoparticles is 4-8wt%, and the loading capacity of the Zn is 3-5wt%.

Three Coordinated Organoaluminum Cation for Rapid and Selective Cyanosilylation of Carbonyls under Solvent-Free Conditions

The well-defined three coordinated electronically unsaturated cationic organoaluminum complex [({(2,6-iPr2C6H3N)P(Ph2)}2N)AlMe]+[MeB(C6F5)3]? (1), has been utilized to catalyze the cyanosilylation of aldehydes and ketones under mild and solvent-free conditions. Moreover, catalyst 1 showed high chemoselective cyanosilylation of aldehydes over ketones, nitriles and olefins. The multinuclear NMR investigations revealed that cyanosilylation proceeds via Lewis adduct formation between 1 and TMSCN thereby activating TMSCN (Si-CN bond) followed by nucleophilic attack of the carbonyl oxygen at the Si center of the activated silane and formation of the product.
