Synthesis and structure of tetraorganylphosphonium arenesulfonates [Ph3PET][OSO2C6H2Me3-2,4,6], [Ph3PET][OSO2C6H3(OH-4)(COOH-3)], [Me4P][OSO2C10H5(OH-1)(NO2)2-2,4], [Ph3PCH2CCH][OSO2C6H3(OH-4)(COOH-3)]

Tetraorganylphosphonium arenesulfonates [Ph3PEt][OSO2С6H2Me3-2,4,6] (1), [Ph3PEt][OSO2C6H4)(COOH-2)] (2), [Me4P][OSO2С10H5(OH-1)(NO2)2-2,4] (3), [Ph3PCH2C≡CH][OSO2C6H3(OH-4)(COOH-3)] (4) were obtained by substitution reaction from tetraorganylphosphonium halides and arenesulfonic acids in water with a yield of up to 90 %. The structure of complexes 1-4 was proven by IR spectroscopy and X-ray diffraction analysis. According to X-ray diffraction data, the crystals of the complexes have an ionic structure and consist of tetraorganylphosphonium cations and arenesulfonate anions.
