Extending the series of p-substituted tetrafluorobenzoic acids: synthesis, properties and structure

The synthesis of the derivatives of p-aminotetrafluorobenzoic acid, p-H2NC6F4CO2H (2b), by hydrolysis, acylation or interaction with aldehydes was developed giving H2NC6F4CO2K (2a), C6F5C(O)N(H)C6F4CO2Et (3) and (E)-ArCH[dbnd]NC6F4CO2Et (4–11). The chemical derivatization of tetrafluoroterephthalic acid, p-HO2CC6F4CO2H (12), by hydrolysis, etherification and reduction was performed giving a number of symmetrical X(O)CC6F4C(O)X (13–15; X?=?Cl, NEt2, OMe) or unsymmetrical YC6F4CO2Me (15a–b, 16, 18–21; Y?=?CO2K, CO2H, CH2OH, C(O)Cl, C(O)C6H3(i-Pr)2, CO2CH2C6F4CO2Me, CO2C6H4Bu-t), HOCH2C6F4CO2H (17), [MeO2CC6F4]2Y (22, 23; Y?=?OCH2CH2O, N(H)C6H4N(H)) compounds. All substances were thoroughly investigated by spectroscopic methods (multinuclear NMR and IR spectroscopy, mass-spectrometry). The molecular structures of p-H2NC6F4CO2Et (2) and p-HO2CC6F4CO2Me (15b) have been determined by X-ray diffraction analysis.
