摘要： A process for fluorinating &bgr;-dicarbonyls to form the corresponding &agr;-fluorinated-&bgr;-dicarbonyl compounds is provided. The process is represented by the following reaction scheme: where R1 is H, alkyl or alkoxy, R2 is H, alkyl or perfluoroalkyl, and R3 is H, Cl, Br, I or alkyl. Use of oxygen in the fluorine stream yields a product which is 90-96% pure and contains radical fluorination impurity levels which are 10-20% lower than when oxygen is not used.

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.
