ABSTRACT:
An ether is oxidized with oxygen under an oxidation catalyst comprising an imide compound (such as N-hydroxyphthalimide) or the imide compound and a co-catalyst to produce the corresponding chain or cyclic ester or anhydride. The co-catalyst may be a transition metal compound. The above process provides a process for oxidizing an ether by oxygen efficiently to produce the corresponding oxide (such as an ester, an hydride) with high conversion and selectivity.
