An interest in ionic liquids unflagging for several decades is related to their application potential [1]. The term ionic liquids (ILs) refers to the compounds consisting of ions with melting point below 100°C [2]. The ILs are usually composed of an organic cation and anions, both organic and inorganic ones [3÷7]. Moreover, the ILs are described as designable compounds because their physicochemical parameters can be controlled through the selection of both a cation and an anion [8]. They are used as environmentally friendly replacements of conventional, volatile solvents in organic synthesis [9] mainly due to their exceptional properties. Radicals are unstable molecules with an unpaired electron in the outer orbit. They usually include reactive forms of oxygen such as superoxide, hydroxyl, peroxyl, alkoxyl radicals and various nitrogen oxides [10]. These compounds perform a double role in biological systems as they may have both a positive and a negative effect on the organism. Their activity inside the cells involves a defence against pathogens; they can also serve as signalling systems [11].
