Method of preparing perfluoro-3-methyl-2-butanone

The invention discloses a method of preparing perfluoro-3-methyl-2-butanone through a reaction of hexafluoropropylene and trifluoroacetyl fluoride under effect of a liquid-phase catalyst which includes a main catalyst, a cocatalyst, an additive and an organic solvent, wherein the main catalyst is selected from metal fluorides and/or metal bifluorides; the cocatalyst is selected from C6-C9 perfluoroolefines; the additive is selected from crown ether and/or crown ether-like compound; the organic solvent is selected from polar aprotic solvents. The preparation method can achieve one-step reaction, is high in reaction speed, and is high in product yield.

Preparation method of perfluoroketone

The invention discloses a preparation method of perfluoroketone. According to the preparation method, in an organic solvent, in the presence of a catalyst metal fluoride and a cosolvent, an addition reaction is performed on perfluoroolefin R1R2C=CR3R4 (R1, R2, R3 and R4 adopt a general formula of CnF2n+1 and n is a non-negative integer set) and acyl fluoride R5-COF (R5 adopts a general formula ofCmF2m+1 and m is a non-negative integer set) to obtain the perfluoroketone CFR3R4-CR1R2-COR5 (R5 is perfluoroalkyl) or CFR3R4-CR1R2-C(O)-CR1R2-CFR3R4 (R5 is an F atom). By the preparation method, theperfluoroolefins and the acyl fluoride are easy to obtain and low in price and the yield of perfluoroketone is high; a route is easy to industrialize.

Catalytic synthesis of certain perfluorinated ketones and study of their structure by 19F NMR spectroscopy

An efficient catalyst of a perfluorinated ketone synthesis of a high selectivity in the absence of solvent was proposed. Products of reaction of perfluorinated fluorides of various structures with tetrafluoroethylene and hexafluoropropylene in the presence of efficient catalysts without solvent were examined. The structure of the resulting products and their isomeric composition were identified by 19F NMR spectrscopy. Pleiades Publishing, Ltd., 2013.

Perfluoro allyl fluorosulfate (FAFS): A versatile building block for new fluoroallylic compounds

In this study we will present and discuss both the synthesis of CF 2=CFCF2OSO2F (perfluoroallyl fluorosulfate, FAFS), focusing in particular on the important role of C3F 6/SO3 ratio, reaction temperature and boron catalyst/SO3 ratio on FAFS' yield and selectivity, as well as a wide variety of ionic and radical reactions possible with FAFS. We focused our attention on reactions of FAFS with aliphatic and aromatic alcohols, acyl halides, halides, H2O2, ketones and radicals whose synthesis and reaction mechanisms will be presented and discussed. Particular attention will be devoted to the novel diallyl-fluoroalkyl peroxide obtained. Factors such as pKa and Lowry and Pearson's Hard/Soft Acid-Base Theory which determine the selectivity between Addition/Elimination vs. Nucleophilic Substitution reaction mechanisms on FAFS will also be presented and discussed.

PREPARATION OF COMPOUNDS HAVING A PERFLUOROALKYLCARBONYL GROUP

Carbonyl fluoride and carboxylic acid fluorides can be added onto perfluoroalkenes, for example hexafiuoropropene, under unpressurized conditions. Perfiuoroalkylcarboxylic acid fluorides or ketones having a perfluoroalkyl group can thus be prepared in a simple way.
