Reductive dechlorination rate constants for five chlorobenzenes in the presence of Pd/Fe as catalyst were determined experimentally. Linear free energy relationships (LFER) for the dechlorination rate constants of five chlorobenzenes and three chlorophenols were developed by partial least squares (PLS) regression based on quantum chemical parameters computed by PM3 Hamiltonian. The optimal LFER model obtained is log k = -1.63 + 1.46 × 10-3ΔHf- 7.69 × 10-1ELUMOwhere k stands for the dechlorination rate constants, AHfis the standard heat of formation, and ELUMOis the energy of the lowest unoccupied molecular orbital. The Qcum2value of the model is 0.879, indicating good robustness and predictive power of the model.
