5458689 RECHARGEABLE LITHIUM BATTERY HAVING A SPECIFIC ELECTROLYTE Kawakami Soichiro; Kobayashi Naoya; Asao Masaya Nara, JAPAN assigned to Canon Kabushiki Kaisha A rechargeable lithium battery comprising at least an anode, a separator,a cathode, and an electrolyte integrated in a battery housing, characterized in that said electrolyte comprises a salt ‘of an organic fluorine-silicon compound containing at least fluorine, silicon and carbon elements as the constituents.
5659046 METHOD FOR THE PREPARATION Z-PERFLUOROALKYL-3-OXA.ZOLIN-5-O NE
OF
Kameswaran Venkataraman Princeton Junction, NJ, UNITED STATES assigned to American Cyanamid Company There is provided a method for the preparation of a 2-peffluoroalkyl-3-oxazolin-5-one compound comprising reacting an aminonitrile with a perfluoroacylating agent in the presence of a solvent to form a perfluoroalkanoyl aminonitrile intermediate and cyclizing the intermediate in the presence of an acid and at least one molar equivalent of water.
4-Fluorothiophenol is obtained in outstanding purifies and yields if 4-fluorobenzenesulphonyl chloride is reacted with sodium hydrogen sulphite solution to give a solution of sodium 4-fluorobenzenesulphinate,this solution is reduced with sulphur dioxide to give 4,4’-difluorodiphenyl disulphide and finally this is reacted with sodium borohydride in a water-miscible inert organic solvent to give 4-fluorothiophenol (sodium salt). Free 4-fluorothiophenol can be isolated from the sodium salt solution by acidification.
