Paragraph 0057; 0062, (2021/07/08)
The invention discloses polyfluoroaryl substituted alkane and a preparation method thereof, and belongs to the field of organic synthesis. The invention solves the problem that the existing synthesis of polyfluoroaryl substituted alkane needs metal catalysis, high temperature, no water, no oxygen and other harsh reaction conditions. The structural general formula of the polyfluoroaryl substituted alkane is shown in the specification. The method comprises the following steps of: adding polyfluorinated aromatic hydrocarbon, MOM protected alcohol, an Ir(ppy)3 photocatalyst, anhydrous potassium carbonate and ethyl 2-mercaptopropionate into an organic solvent at room temperature, uniformly mixing, carrying out illumination reaction, removing the solvent through reduced pressure distillation, and carrying out silica gel column chromatography separation and purification to obtain the polyfluoroaryl substituted alkane.

P4VPy–CuO nanoparticles were synthesized using ultrasound irradiations. Relevant properties of the synthesized nanoparticles were investigated by X-ray diffraction, scanning electron microscopy, transmission electron microscopy and Fourier transform infrared spectroscopy. After identification, the prepared reagent was used for the promotion of different types of protection reactions of alcohols, phenols and amines. Easy workup, short reaction times, excellent yields, relatively low cost and reusability of the catalyst are the striking features of the reported methods.
