Herein we report Ni(II) complexes supported by a tetradentate amido-quinoline ligands which was found to effectively catalyze C-H chlorination of a series of alkanes having C-H bond dissociation energies ranging from 99.3 kcal mol-1 (cyclohexane) to 87. kcal mol-1 (ethyl benzene) using NaOCl as chlorine source giving exclusively chlorinated products without any hydroxylated products. The complexes were selective towards C-H bond chlorination thus mimicking the activity of halogenase enzyme (Figure 1).
