In the work on the example of liquid-phase catalytic processes of the aromatic C-Cl bonds activation occurring in the presence of nickel complexes under reducing conditions the main effects arising from the replacement of aprotic dipolar solvents with ionic liquids are analyzed. The features of the nickel-catalyzed reaction of aryl chlorides, related to the nature of the anion and cation of the ionic liquid, were observed. It was shown that a high concentration of cations and anions in the ionic liquid affects the process of reduction of the nickel complex to the catalytically active state. In addition, the presence of a reactive hydrogen atom in the imidazolium cation of ionic liquid causes the process of hydrodechlorination of aryl chlorides.
