The reactions of 4-substituted-polyfluorinated-[(difluoromethyl)sulfinyl]benzenes ([4-X-C6F4S(O)CHF2 [X = H, CF3 and C6F5S(O)]) with phenolate anion in benzene, Et2O and CH3CN have been investigated. The reactions of the substrate (X = H, CF3) and sodium phenolate in equal amounts resulted in the formation of mixtures of the starting compound, 2-phenoxyderivative and disubstituted products. The two-fold amount of the phenolate afforded the 2,6-disubstituted products for X = H in MeCN and for X = CF3 in Et2O. At the same time, 4-CF3-C6F4S(O)CHF2 in CH3CN gave a mixture of the 2,6- and 2,5-bis(phenoxy) derivatives. Quantum chemical calculations have been performed to explain this phenomenon. For X = C 6 F 5 S(0) in MeCN, the reaction was accompanied by sulfinyl moiety ipso-substitution. [GRAPHICS] .
