Versuchsvorschrift

The preparation of 2-propenylphenol from phenol and allyl bromide is similar to that outlined1. The reaction of this compound with dibromomethane is similar to that described above for di (N-phenylcarboxaldimine-4-phenoxy)methane. The title compound was extracted with ether 3×100 ml portions from the aqueous dimethylformamide solution, washed with aqueous potassium hydroxide (10%) and then water. The ether phase was dried over sodium sulphate and the solvent was stripped off under reduced pressure. The oil which contained some (~5%) of a less polar component and at least two isomeric forms of the title compound, as indicated from high pressure liquid chromatography, was used without further purification in the reaction below.
