摘要:
Novel compositions containing SF4—O—CF3 bonded to an organic group are disclosed. Aryl trifluoromethoxytetrafluorosulfuranes (or Ar—SF4—O—CF3), have been synthesized via the reaction of an aryl disulfide or thiol with fluoroxytrifluoromethane (F3COF). The compositions are useful synthons, which may be derivatized to yield highly electrically polar molecules, particularly novel liquid crystal compositions having high dielectric anisotropies. Cycloalkyl trifluoromethoxytetrafluorosulfuranes have similar utility.
摘要:
The present invention relates to lithium secondary batteries comprising a negative electrode, a positive electrode, a separator and a lithium-based electrolyte carried in an aprotic solvent, and to the electrolyte compositions, and to methods for purifying battery active materials. The electrolyte comprises at least one solvent and a lithium salt of the formula: Li2B12FxH12-x-yZywhere x+y is from 3 to 12, and x and y are independently from 0 to 12, and Z comprises at least one of Cl and Br.
