COMPOSITES, METHODS AND USES THEREOF

The present invention relates, in general terms, to methods of catalysing a reaction, including the steps of contacting a chemical entity comprising a sulphide moiety with a composite and an oxidant. The composite acts as a heterogeneous catalyst to oxidise the sulphide moiety. The present invention also relates to composites, methods of synthesising the composites and its use as a catalyst thereof.

Rational Design and Development of Low-Price, Scalable, Shelf-Stable and Broadly Applicable Electrophilic Sulfonium Ylide-Based Trifluoromethylating Reagents

The development of two highly reactive electrophilic trifluoromethylating reagents (trifluoromethyl)(4-nitrophenyl)bis(carbomethoxy)methylide (1g) and (trifluoromethyl)(3-chlorophenyl)bis(carbomethoxy)methylide (1j) through structure-activity study was described. Under mild conditions, reagent 1g reacted with β-ketoesters and silyl enol ethers to give α-trifluoromethylated-β-ketoesters or α-trifluoromethylated ketones in high yields. In addition, reagent 1g could serve as a trifluoromethyl radical for a variety of trifluoromethylative transformations under visible light irradiation, including radical trifluoromethylation of electron-rich indoles and pyrroles and sodium aryl sulfinates as well as trifluoromethylative difunctionalization with styrene derivatives. On the other hand, as a complimentary, under reductive coupling conditions, reagent 1j reacted with a variety of (hetero)aryl iodides for the formation of trifluoromethylated (hetero)arenes.

Trifluoroalkyl sulfone compound preparation method

The invention provides a trifluoroalkyl sulfone compound preparation method, which comprises: continuously feeding a trifluoroalkyl thioether compound, sodium tungstate dihydrate and a hydrogen peroxide solution into a continuous reactor through feeding equipment, and carrying out an oxidation reaction on the trifluoroalkyl thioether compound to obtain a product system containing the trifluoroalkyl sulfone compound, wherein the trifluoroalkyl thioether compound has a structure represented by a structural formula, R is any one selected from the following groups: linear alkyl, branched alkyl, substituted aryl, non-substituted aryl, substituted heterocyclic aryl, non-substituted heterocyclic aryl, non-substituted cyclic alkyl and substituted cyclic alkyl, and the temperature of the oxidationreaction is 25-50 DEG C. According to the invention, by using the continuous feeding, the material contact effect is improved, so that the thioether oxidation reaction can be carried out at a low temperature; and the oxidation reaction temperature is reduced to effectively reduce the decomposition of hydrogen peroxide and reduce the pressure resistance requirement on the continuous reactor.
