Alkyltriphenylphosphonium arenesulfonates [Ph3PEt][OSO2С6H4(СOOH-2)] (1), [Ph3PС3H5-cyclo][OSO2Naf-1] (2), [Ph3PСH2СN][OSO2С6H2(Me3-2,4,6] (3), [Ph3PCH2C≡CH][OSO2C6H4(COOH-2)] (4), [Ph3PCH2OH][OSO2C6H3(OH-4)(COOH-3)] (5), [Ph3PCH2OH] [OSO2С6H3(Cl2-2,5] ∙ H2O (6) were obtained by substitution reaction from tetraorganylphosphonium halides and arenesulfonic acids in water, yielding up to 90%. The structure of complexes 1-6 was proven by IR spectroscopy and X-ray diffraction analysis. According to the X-ray diffraction data, crystals of the complexes have ionic structure and consist of tetraorganylphosphonium cations and arenesulfonate anions.
