The present authors, recently, have carried out an extensive study on the oxidative cleavage of various compounds with peracetic acid, and it has been found that the hydroaromatic ring was readily dehydrogenated by peracetic acid. Our previous reports1) indicated that the oxidative cleavage of dialin proceeded in two different reactions in an initial stage; the one was epoxidation and the other, dehydrogenation. On the contrary, the oxidative cleavage ...
