Preparation method of o-trifluoromethylbenzamide

The present invention discloses a method for preparing o-trifluoromethyl benzamide. The preparation method comprises the following steps: (1) in an organic solvent, the 2-nitrobenzotrifluoride and fluorinated salts are denitrified as shown below to obtain o-fluorobenzotrifluoride; (2) in an organic solvent, the o-fluortrifluorotoluene and cyanidylation reagent are defluoride cyanidation reaction as shown below to obtain o-trifluoromethylbenzonitrile; (3) in the presence of alkali, the o-trifluoromethylbenzonitrile, hydrogen peroxide hydrolysis reaction as shown below. The preparation method is simple to treat, the product purity is high, the impurities are small, and the yield is high.

Reactions of aromatic compounds with xenon difluoride

Reactions of substituted benzenes C6H5R (R = Me, F, Cl, Br, CF3, NO2) with xenon difluoride in the presence of boron trifluoride–diethyl ether complex in weakly acidic (1,1,1,3,3-pentafluorobutane) and weakly basic media (acetonitrile) have been studied. These reactions lead to the formation of fluorobenzene derivatives FC6H4R (isomer mixture) together with isomeric difluorobenzenes and fluorinated and non-fluorinated biphenyls. The results have been compared with previously reported data obtained in other solvents using other catalysts.

A catalytic borylation/dehalogenation route to o -fluoro arylboronates

A two-step Ir-catalyzed borylation/Pd-catalyzed dehalogenation sequence allows for the net synthesis of fluoroarenes where the boronic ester is ortho to fluorine. Key elements of this approach include the use of a halogen para to the fluorine to block meta Ir-catalyzed borylation and the chemoselective Pd-catalyzed dehalogenation by KF activated polymethylhydrosiloxane (PMHS).
