Abstract
Lithium fluoride, prepared in situ from lithium chloride and trimethytin fluoride, reacts with organotitanium fluoride, giving the first soluble lithium fluoride derivat. In the solid state, according to the X-ray structure analysis, lithium is coordinated by four fluorine atoms. The solubility is provided by pentamethycyclopentadienyl ligads bonded to the titanium atoms. In the solution a dissociation equilibrium exists which was characterised by NMR spectroscopy and the thermodynamic parameters were determinated. Organofluorotitanoxanes react with trialkyl- in triarylaluminijem with the substitution of of fluorine atoms by organic groups. The prepared compounds were characterised by NMR and IR spectroscopy and X-ray crystal structure analysis. Calcium fluoride, prepared in situ, reacts with organotitanium fluoride. Calcium atom in the products is coordinated by eight fluorine atoomsand is coordinativelly unsaturated. It reacts with hexamethyphophortriamide, tetrahydrofuran giving adducts as well as interacts with chloroform as determined by NMR spectroscopy and X-ray structural analysis. Lutidinium organofluorotitanate was prepared by the reaction of lutidinium-hydrogen fluoride adduct and organotitanonium fluoride. It reacts with lanthanum trifluoromethansulfonate and strontium iodide respectively giving the compounds with lanthan and strontum atom in the fluorine environment of the molecular compound. The compounds were charactrerised by spectroscopic and diffraction methods.
