Hydroxycarboxylation, oxidative radical

Fig. 20 Oxidative radical hydroxycarboxylation reactions catalyzed by (phthalocyanine)iron (The depiction of the hydroperoxyl radical is formal to account for the correct proton and electron balance. Another formal hydroperoxyl radical (not shown for clarity) results from coupling of the initially generated superoxide and the proton resulting from formation of the azo radical)...
