Versuchsvorschrift

To a stirred solution of 2.5 g. of 3,7,11,11-tetramethyltrideca-2,4-dienoic acid in 30 ml. of dry ether is added slowly, at 0°, 23 ml. of a one molar solution of ethyl lithium in benzene. After about three hours at 20°, the mixture is poured into iced 1N hydrochloric acid (100 ml.) with vigorous stirring. The ether layer is separated, combined with ethereal washings of the aqueous phase, washed with water, saturated potassium bicarbonate, and then saturated brine, dried over magnesium sulfate and concentrated under reduced pressure to yield 5,9,13,13-tetramethylpentadeca-4,6-dien-3-one which is purified by high vacuum distillation or chromatography.
