Abstract : A self-consistent set of sigma constants was developed to obtain linear free energy relations with titanium tetrafluoride complexes of the aromatic amine oxides. Several series of the diadducts of titanium tetrafluoride were studied with high-resolution fluorine-19 nuclear magnetic resonance spectroscopy. These series consisted of fluorotitanate complexes of formula TiF4.2(donor) and TiF5.(donor)(-), where donor represents an organic molecule (Lewis base) which coordinates through oxygen. The TiF4.2(donor) adducts included both TiF4.2D complexes in which the donors are identical, and TiF4.D,D' complexes, in which D and D' represent different Lewis bases. Cis-trans isomerism of the diadducts of TiF4 was also studied. Some complexes of TiF4 with substituted pyridines were also investigated. Fluorine-19 chemical shifts and spin-spin coupling constants were determined for most of the fluorotitanate complexes. The temperature dependence of the TiF4.2D spectra was also studied. The low infrared spectra of some SnF4.2D and TiF4.2D were also obtained. (Author)
