http://ursula.chem.yale.edu/~chem220/chem220js/STUDYAIDS/ozonolysis/Oz.html Alkenes can be oxidized with ozone to form alcohols, aldehydes or ketones, or carboxylic acids. In a typical procedure, ozone is bubbled through a solution of the alkene in methanol at −78 °C until the solution takes on a characteristic blue color, which is due to unreacted ozone. This indicates complete consumption of the alkene. Alternatively, various other chemicals can be used as indicators of …

Webb(Oxidative ozonolysis) Oxidising alkenes with ozone can form alcohols, aldehydes, ketones and carboxylic acids. In the ozonolysis of alkenes process, ozone is bubbled through an alkene solution in methanol at 78°C until the solution turns a characteristic blue colour due to unreacted ozone. WebbOzonolysis is an efficient way of oxidizing alkenes (and alkynes as well) into their corresponding aldehydes and ketones:. One of the advantages of ozonolysis compared to other oxidative cleavage reactions is that it does not over-oxidize the alkene to carboxylic acid unlike, for example, the potassium permanganate (KMnO4):. Even for terminal …
