Procedure

To 8.5 g. of pure 5,5-dimethyl-4-oxo-2-hexenoic acid in 150 ml. of diethyl ether was applied irradiation from a 300 watt sun-lamp. The solution was in a 500 ml. Pyrex flask, and the lamp was placed 5 cm. from the flask. The light emitted by the lamp was primarily of wave length 200 to 800 mμ. The irradiation was continued for about 18 hours. The mixture was then evaporated under vacuum to obtain 8.5 g. of the desired product as colorless crystals.
