Article abstract of DOI:10.1021/j100450a009

Surface reactions between simple alkenes and O3^- ions on MgO were observed at 25 deg C.Following the reaction of ethylene or propylene with O3^-, CO2 and CH4 were detected as major products upon heating the sample.The reaction of cis-2-butene with O3^- resulted in the formation of butadiene and oxygen-containing organic compounds, as well as CO2 and CH4.Thermal desorption patterns and infrared spectra of surface complexes suggest that carboxylate ions are intermediates in the formation of CO2 and CH4 and peroxy radicals are intermediates in the formation of oxygen-containing organic molecules.
