the autoxidation of aldehydes having tertiary formyl groups has been investigated. These afford nor-derivatives by loss of carbon monoxide, and carboxylic acids. Steric interactions have been shown to affect strongly the ratio between carboxylic acid and nor-derivatives and, in addition, to increase the autoxidation rate. For the first time, formation of formates from aldehydes by autoxidation conditions

Treatment of carboxylic acids with hydrogen peroxide in the presence of a mercury (II) salts results in oxidative decarboxylation and is an effective method for transformation of the carboxylic acids into the corresponding nor-derivatives, hydroperoxides and alcohols. Oxidative decarboxylation of acetyloleanolic, acetylursolic and dehydroabietic acids is described.
