The overall rate constants for H‐abstraction ( k H ) from tetrahydrofuran and D‐abstraction ( k D ) from fully deuterated tetrahydrofuran by chlorine atoms in the temperature range of 298‐547 K were determined. In both cases, very weak negative temperature dependences of the overall rate constants were observed, described by the expressions: k H = (1.55 ± 0.13) × 10 −10 exp(52 ± 28/ T ) cm 3 molecule −1 s −1 and k D = (1.27 ± 0.25) × 10 −10 exp(55 ± 62/ T ) cm 3 molecule −1 s −1 . The experimental results show that the value of the kinetic isotope effect ( k H / k D ), amounting to 1.21 ± 0.10, is temperature independent at 298‐547 K.
