Procedure

3,8 g. of lead acetate in 100 ml. of pyridine are treated with 69 g. of β-isophorone. The mixture is gassed with oxygen at 70° C. for 2 hours with intensive stirring and subsequently worked up by distillation. [b.p. 62°-64° C., 0,2 Torr]. The conversion of β-isophorone used amounts to 31 g. corresponding 45%. Ketoisophorone is obtained in a yield of 26 g. corresponding to 76%.
