Acetylacetone–Fe catalyst modified by imidazole ionic compound and its application in aerobic oxidation of β-isophorone

Traditional acetylacetone–Fe catalyst modified by imidazole ionic compound was synthesized and used in the oxidation of β-isophorone. Compared with the traditional acetylacetone–Fe, it was found that the modified acetylacetone–Fe catalyst was reusable, more effective and stable, which provides a new way for making more powerful and greener acetylacetone metal catalyst for chemical industry.
