3,5 g. of chromium (III) acetylacetonate 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. The conversion of β-isophorone used amounts to 49,6 g. corresponding to 72%. Ketoisophorone is obtained in a yield of 41 g. corresponding to 75%.
