実験手順
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).
