Relative rate constants for the reactions of trichloropropenyl radical. Application of the two‐parameter Taft equation

The relative rate constants for the hydrogen atom abstraction by CCl3CHCH· radical from CH2Cl2, CHCl3, CH3COCH3, CH3CN, C6H5CH3, C6H5OCH3, CH3CHO, and CH3OH in the liquid phase at 20°C have been measured. It was shown that these reaction rate constants are correlated by the two‐parameter Taft equation with ρ* = 0.726 ± 0.096, r* = 1.22 ± 0.16. A relationship between r* and bond dissociation energy D(RH) has been found for the abstraction reactions of different free radicals.
