Carbonyl products of the gas phase reaction of ozone with C5-C7 alkenes

Article Abstract:

Primary carbonyl formation yields of the reaction of ozone with C5-C7 1-alkenes and 2,3-dimethyl-1-butene were close to the value of 1.0, which is consistent with the mechanism O3 + R1R2C = CH2 leading to alpha(HCHO + R1R2-COO) + (1-alpha)(R1COR2 + H2COO), where HCHO and R1-COR2 are the primary carbonyls. This was found in a study of the gas phase reaction of ozone with alkenes, using liquid chromatography and chemical ionization mass ionization to identify carbonyl products.
