Stopped-Flow Studies of the Mechanisms of Ozone-Alkene Reactions in the Gas Phase: trans-2-Butene

Article abstract of DOI:10.1021/j100327a017

The reaction of ozone with trans-2-butene has been studied in the gas phase at 294 K and 530 Pa (4 Torr) by using a stopped-flow reactor coupled to a photoionization mass spectrometer.The concentrations of reactants and products were determined as a function of reaction time.A mechanism is proposed to account for the observed products: CH3CHO, H2CO, CO2, CH4, CF3C(O)C(H)(OH)CH3, H2C=C=O, H2O, 2-butanone, 2,3-epoxybutane, CH3C(O)C(O)CH3, and HC(O)C(O)H.This work again indicates that simple "hot" ester hypothesis needs to be critically reconsidered for gas-phase ozonolysis.
