Versuchsvorschrift

0.1 moles 4,4'bis(chloromethyl)biphenyl (prepared by method A above), 0.25 moles potassium acetate and 100 mls glacial acetic acid were reflux for 17 hours with stirring. The reaction mixture was filtered and the filtrate evaporated to dryness at 80° C. under water pump vaccum. The residue was recrystallised from methanol to yield 0.068 moles product=68 percent of theory.
