Procedure
The procedure of Example 1 was used except that 20 g 4,4'-difluorodiphenylmethane, 30 g water, 31 g MnO2 and 50 g H2 SO4 were used. 20 g off-white solids, after toluene removal, afforded 95% pure 4,4'-difluorobenzophenone in a 90% yield.
Workup
- custom20 g off-white solids, after toluene removal
