Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Water | HCID 962 | — |
| Reactant | 1,1'-Methylenebis[4-fluorobenzene] | HCID 96094 | — |
| Catalyst | Manganese dioxide | HCID 14801 | — |
| Product | 4,4'-Difluorobenzophenone | HCID 9582 | 95% |
Reaction Steps
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.
