A procedure was developed for oxidation of 4',4aEuro(3)-bis(2-carboxybenzoyl)diphenyl sulfide with per acids (peracetic and trifluoroperacetic). The 4',4aEuro(3)-bis(2-carboxybenzoyl)diphenyl sulfone obtained was converted into pseudodichloride, and three new polyarylenephthalides with regular alternation of the electron-acceptor (diphenyl sulfone) and electron-donor (diphenyl oxide, diphenyl sulfide, terphenyl) fragments were synthesized on its basis. The synthesized monomers can be used in the synthesis of new polyarylenephthalides exhibiting the electronic switching effect.
