الإجراء التجريبي

t-Butylhypochlorite (104.6 g, 0196 mol) was added dropwise to a solution of 2-allyl-1,3-cyclohexanedione (132 g, 0.87 mol) in 650 ml of methanol at 0° C. The temperature was not allowed to rise above 20° C. The methanol was removed at reduced pressure in a 40° water bath and the residual oil was taken up in benzene. The benzene solution was washed with 5 percent sodium thiosulfate (3×250 ml), 5 percent sodium bicarbonate (3×250 ml) and water (1×250 ml). Evaporation of the benzene gave 148 g (91 percent) of 2-chloro-2-allyl-1,3-cyclohexanedione as a light yellow oil.
