Ozonólisis de alquenos
R2C=CR2 + O3 → R2C=O + R2C=O
Descripción general
Ozone cleaves carbon-carbon double bonds to form carbonyl compounds (aldehydes and/or ketones). The reaction proceeds through a molozonide intermediate that rearranges to an ozonide, which is then reduced. Ozonolysis is used to determine alkene double bond positions by identifying the carbonyl fragments.
Ejemplo cotidiano
Ozonolysis is used in forensic chemistry to determine the structure of unknown alkenes by analyzing the fragments produced.
