Here are some examples: Ethene + … WebbOzone reacts with an alkene via a cycloaddition reaction to form an unstable 5-membered ring called a molozonide. In the mechanism shown below, two C-O bonds are formed and the p-bond of the alkene is broken. The process is a syn addition of the electrophile ozone to the nucleophilic alkene.
WebbOzonolysis is a pretreatment technique used for decreasing the lignin content in lignocellulosic biomass. It mainly reduces lignin and hardly affects cellulose and hemicellulose. Vidal and Molinier designed and developed a small-scale laboratory ozonolysis setup. This process has to be performed at ambient pressure and temperature.
