Abstract

Novel hexafluoroisopropylboranes (CF3)(CF2H)CFBH2·L and -borate anions [(CF3)(CF2H)CFBH2X]− with Lewis basic heterocyclic ligands L and the anionic substituents X = F− and CN− were obtained. The syntheses were accomplished by substitution reactions of the dimethyl sulfide adduct (CF3)(CF2H)CFBH2·SMe2, which was synthesized on a large scale. The hexafluoroisopropylboranes and -borates were characterized by NMR and vibrational spectroscopy, elemental analysis, and single-crystal X-ray diffraction. In addition, the thermal and electrochemical stabilities were investigated by DSC measurements and cyclic voltammetry and selected experimental data and trends are compared with theoretical ones.
