Participants

Reaction Steps

11.4 g (0.05 mole) of 1-(4-chlorophenoxy)-3,3-dimethyl-butan-2-ol were added to a mixture of 14.7 g (0.05 mole) of potassium dichromate in 12.25 g of sulphuric acid and 73.5 g of water at 30° C., whereupon the temperature rose to about 45° C. The mixture was stirred overnight at room temperature and then extracted three times with ether. The combined organic phases were washed with sodium bicarbonate and water, dried over sodium sulphate and concentrated. 7.8 g (69% of theory) of 1-(4-chlorophenoxy)-3,3-dimethyl-butan-2-one of melting point 58° C. were obtained. ##STR25##
