Reaktionsschritte

56.0 g (0.5 mole) of potassium tert.-butylate are added to a mixture of 50.0 g (0.5 mole) of pinacolone and 42.0 g (0.5 mole) of methyl formate at 15° to 20° C., with cooling. The reaction mixture is subsequently stirred at 30° C. for 12 hours. For working up, 400 ml of diethyl ether are added and the product precipitated is filtered off with suction and dried. 62.3 g (75% of theory) of 4,4-dimethyl-1-hydroxy-1-penten-3-one, as the potassium salt, are obtained in the form of a light yellow powder.
