Yamada, Shigeyuki,Knochel, Paul
experimental part, p. 2490 - 2494 (2010/09/04)
Functionalized aryl- or heteroarylmagnesium reagents, prepared from the corresponding bromides or iodides using halogen-magnesium exchange or direct magnesium insertion in the presence of lithium chloride, reacted smoothly with N-fluorobenzenesulfonimide, (PhSO2)2NF, in the mixed solvent (4:1 CH2Cl2-perfluorodecalin) to give the corresponding aromatic fluorides in moderate to good yields.

supporting information; experimental part, p. 2215 - 2218 (2010/06/19)
"Chemical Equation Presented" Cive me an "F": Electrophilic fluorination of various aromatic and heteroaromatic Grignard reagents is smoothly performed with (PhSO2)2NF as fluorinating agent in a 4:1 mixture of CH2Cl2/ perfluorodecalin (see scheme). This solvent system allows minimization of most side reactions.

The preparation of 3,4-difluorobenzotrifluoride from 3,4-dichlorobenzotrifluoride by a KF exchange reaction is described.The conversion of 3,4-difluorobenzotrifluoride to 3,4-difluorobenzoic acid and derivatives is also reported.
Preparation of 3,4-difluorobenzotrifluoride

, (2008/06/13)
3,4-Difluorobenzotrifluoride is prepared by contacting a 3,4-dihalobenzotrifluoride with an effective amount of KF or CsF in a polar aprotic solvent at an elevated temperature under substantially anhydrous conditions. The product can be removed as it is formed or the reaction may be run at the autogenous pressures generated by the reaction mixture in a sealed reactor.
