A STUDY OF THE VAPOR PHASE REACTION OF OZONE WITH OLEFINS IN THE PRESENCE AND ABSENCE OF MOLECULAR OXYGEN

Relative rates of reaction of ozone with a number of olefins in the vapor phase have been determined at room temperature in the presence and absence of molecular oxygen. In the absence of oxygen the rates appear to follow more closely an electrophilic trend, although some of the deviations observed previously in the presence of oxygen still persist to some extent. The ratio of olefin to ozone consumed is unity in the absence of oxygen and varies from about 1.4 to 2 in its presence. In the presence of molecular oxygen, therefore, a secondary attack on the olefins takes place as well. The yields of products are similarly affected.
