Pridatko S. Boron tribromide adducts and their acid-catalitic properties in non-aqueous oxygen-contaning solvents

The object is oxygen-contaning boron tribromide and mixed boron galogens complexes. The thesis is devoted to studying the proces of complex formation and state of boron halogens in organic non-aqueous oxygen-contaning solvents and research into acid and catalic activity. Sufficient experimental proof (NMR,DTA,EPR) of the mechanism and direction of the oxygen-contaning boron tribromide adducts has been obtained. The location of cationic and anionic forms of boron halogens in aprotonic acids activity series has been estimated. The experimental data of the kinetics investigation confirmed the possibility of regulation of acid and catalic of boron halogens. Inhibiting influence of anions [BBr4]- and [BF2Br2]- upon catalic of boron tribromide has been shown.
