Preparation method of trifluoroacetophenone derivative

The invention relates to the field of organic synthesis, in particular to a preparation method of a trifluoroacetophenone derivative. Substituted aniline is used as a raw material, and preparation of the trifluoroacetophenone derivative is completed through three steps including diazotization reaction, coupling reaction and hydrolysis reaction. The preparation method has the advantages of simple process, high yield and less three wastes generated by the whole reaction, and is suitable for large-scale industrial production.

Palladium-Catalyzed Trimethylenemethane Cycloaddition of Olefins Activated by the δ-Electron-Withdrawing Trifluoromethyl Group

α-Trifluoromethyl-styrenes, trifluoromethyl-enynes, and dienes undergo palladium-catalyzed trimethylenemethane cycloadditions under mild reaction conditions. The trifluoromethyl group serves as a unique δ-electron-withdrawing group for the activation of the olefin toward the cycloaddition. This method allows for the formation of exomethylene cyclopentanes bearing a quaternary center substituted by the trifluoromethyl group, compounds of interest for the pharmaceutical, agrochemical, and materials industries. In the diene series, the cycloaddition operates in a [3 + 4] and/or [3 + 2] manner to give rise to seven- and/or five-membered rings. This transformation greatly improves the scope of the TMM cycloaddition technology and provides invaluable insights into the reaction mechanism.

Hydration of Trifluoroacetophenone Derivatives as Studied by IR Spectroscopy

The characteristics of the hydration reaction of four trifluoroacetophenone (L) derivatives were determined by IR spectroscopy.A correlation was found between the position of the O-H band maximum for the hydrated L form and the Hammett constant of the sub
