Free radical substitution in aliphatic compounds. Part XXIII. The gas phase chlorination of chlorocycloheptane and fluorocyclohexane

Abstract

The chlorination of chlorocycloheptane and fluorocyclohexane have been studied in the gas phase over the temperature range 70–200°. The trans to cis ratio of the products derived from chlorine atom attack at the 2-position was 41:1 for 1,2-chlorofluorocyclohexane and 5:1 for 1,2-dichlorocycloheptane. These results are considered in the light of current theories relating to the high trans/cis ratios observed.
