2,4'-Difluorobenzophenone → 1-Fluoro-2-[1-(4-fluorophenyl)ethenyl]benzene
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 2,4'-Difluorobenzophenone | HCID 67651 | — |
| Reactant | 2-Chloro-4'-fluorobenzophenone | HCID 74547 | — |
| Product | 1-Fluoro-2-[1-(4-fluorophenyl)ethenyl]benzene | HCID 13235785 | 85% |
Reaction Steps
The procedure described in Example 1 is repeated except that the 130 parts of 2-chloro-4'-fluorobenzophenone are replaced by 168 parts of 2,4'-difluorobenzophenone, which was converted into the title compound in 85% yield. Distillation, under vacuum, gives a colourless liquid which is pure 1-(2-fluorophenyl)-1-(4-fluorophenyl)ethene (b.pt. 82°/0.2 mm Hg).
