The relative rate constants for the hydrogen atom abstraction by CCl 3 CHCH· radical from CH 2 Cl 2 , CHCl 3 , CH 3 COCH 3 , CH 3 CN, C 6 H 5 CH 3 , C 6 H 5 OCH 3 , CH 3 CHO, and CH 3 OH 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 (RH) has been found for the abstraction reactions of different free radicals.
