Versuchsvorschrift
1 g. of 3-(3',4'-dichloro-4-biphenylyl)-3-hydroxybutyric acid and 0.1 g. of p-toluenesulfonic acid in 35 ml. of toluene are heated under reflux for 3 hours and water by-product is removed. The reaction mixture is worked up to give 3-(3',4'-dichloro-4-biphenylyl)-2-butenoic acid.
Aufarbeitung
- temperatureunder reflux for 3 hours
- customwater by-product is removed
