3-Aryloxindole derivatives were synthesized through a Friedel-Crafts-type cyclization. The reaction was catalyzed by a trimethylsilyl tricyanopalladate complex generated in situ from trimethylsilyl cyanide and Pd(OAc) 2. Wide varieties of diethyl phosphates derived from N -arylmandelamides were converted almost quantitatively into oxindoles. When N, N -dibenzylamide was used instead of an anilide substrate, a benzo-fused δ-lactam was obtained. An oxindole product was subjected to substitution reactions to afford 3,3-diaryloxindoles with two different aryl groups.

An efficient synthesis of a variety of 2-arylacetonitriles containing a fluorinated stereogenic center through organo-catalyzed Michael addition reaction of 2-fluoro-2-arylacetonitriles has been developed. This protocol uses a cheap organocatalyst (DBU) and has a broad substrate scope: α, β-unsaturated ketones, esters, nitriles and sulfones were all successfully reacted. Importantly, water proved to be a good solvent for this reaction.

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%.
