In the presence of (1) an oxidation catalyst comprising a crystalline complex of manganese with an N,N'-disalicylidenediamine (e.g. N,N'-disalicylidene C2-8 alkylenediamines and N,N'-disalicylidene C6-12 arylenediamines), or (2) an oxidation catalyst comprising the above complex and a basic nitrogen-containing compound, a substrate (e.g., beta-isophorone or a derivative thereof) is oxidized with molecular oxygen to produce a corresponding oxide (e.g., ketoisophorone). Ketoisophorone can be obtained from beta-isophorone with high conversion and high selectivity.
