Competitive chlorination–dehydrochlorination of 1,1,1,2‐C2H2Cl4

The competitive photochlorination and chlorine photosensitized dehydrochlorination of 1,1,1,2‐C2H2Cl4 have been studied over the temperature range of 349.4–404.5 K after less than 1% conversion. The results are discussed and a value of (Formula Presented.) is proposed for the reaction (Formula Presented.) This result, combined with existing thermochemical data, indicates that there is no evidence of an activation energy for the addition of a Cl atom on the most chlorinated carbon in trichloroethylene: in that case the selectivity of the addition of Cl on the less chlorinated carbon should not depend on temperature.
