WebThe formation of the energy-rich species represented by AB † is easy enough to understand if the energy derives from chemical reaction, as it might do in the formation of the intermediate ozonide in reaction [IX]. Photochemical excitation, to be discussed later in this article, is another way in which an energy-rich species might be formed. WebThe resulting ozonide intermediate is decomposed to alcohols or aldehydes via reductive work-up or to acids by oxidative work-up. Azaleic, adipic, and brassylic acids are obtained from ozonolysis of oleic, petroselinic, and erucic acids employing hydrogen peroxide during an oxidative work-up procedure. WebOzonolysis is a useful technique for the synthesis of carbonyl compounds from alkenes he reductive ozonolysis reaction involves the addition of ozone to an alkene to form an ozonide intermediate. The ozonide is then treated with a reducing agent, such as zinc or sodium borohydride, which breaks the ozonide into smaller molecules. brett meador wikipedia
