The autoxidation of a mixture of 1,2-disubstituted pyrazolidine-3,5-diones 1 and alkenes 2 in the presence of a catalytic amount of manganese(III) acetate dihydrate in air gave 4,4-bis(2-hydroperoxyalkyl)pyrazolidine-3,5-diones 3 in 75-96% yields. The structure of the bis(2-hydroperoxyethyl)pyrazoli
