Oxidation of hydrocarbons. IV. Kinetics and mechanism of the oxidative cleavage of cinnamic acid by acidic permanganate

“…3,4 Alternatively the hypomanganate ester, 1, may be oxidized by permanganate or another cooxidant to the corresponding cyclic manganate ester, 5. It is likely that 5 would decompose to give cleavage products (eq 5) since it is known, for example, that manganate readily may simply be that of converting the cyclic hypomanganate ester to the corresponding cyclic manganate ester.…”
