FIELD: organic chemistry.

SUBSTANCE: invention relates to new ionic liquids designated for using in electrochemical cells and in organic synthesis. Invention describes ionic liquids of the general formula: K⁺A^- (I) wherein K⁺ represents one of cations of the group consisting of the following formulae: wherein R¹-R⁵ can be similar or different and can be bound to one another by a simple or double bond also, and each of them separately or in common can represent the following values: hydrogen atom (H), halogen atom, (C₁-C₈)-alkyl radical that can be partially or completely substituted with the following groups but preferably with fluorine atom (F), chlorine atom (Cl), N-[C_nF_(2n+1-x)H_x]₂, O-[C_nF_(2n+1-x)H_x], SO₂-[C_nF_(2n+1-x)H_x] or C_nF_(2n+1-x)H_x wherein 1 < n < 6 and 0 < x < 2n+1; A^- means anion taken among the group consisting of [PF_x(C_yF_(2y+1-z)H_z)_6-x]^- wherein 1 ≤ x ≤ 6, 1 ≤ y ≤ 8 and 0 ≤ z ≤ 2y+1. Invention provides the development of ionic liquids showing broad range of liquid state, high thermal resistance and low corrosive activity.

EFFECT: improved and valuable properties of ionic liquids.
