Ozonides with nitric acid

Azelaic acid can be prepared by the oxidation of castor oil with nitric acid by the oxidation of ricinoleic acid with nitric acid and with alkaline permanganate by the oxidation of methyl oleate with alkaline permanganate by the ozonization of oleic acid and decomposition of the ozonide by the ozonization of methyl ricinoleate and decomposition of the ozonide by the action of carbon dioxide upon 1,7-heptamethylene magnesium bromide by the hydrolysis of i,7-di(yanoheptane. ... 

The oxidative decomposition of ozonides is further accomplished by their treatment with hydrogen peroxide [97] in the presence of formic acid [95, 99] or acetic acid [102, 103] or with silver oxide and nitric acid [77] (equations 109-112).
