obutane), and lower yields of other products including perfluoro-(1,2-bisdimethylaminocyclobutane), perfluoro-(2,2′-dimethoxybicyclobutyl), and perfluoro-(2-dimethylamino-2′-methoxybicyclobutyl). Reaction with perfluorobut-2-ene is more complex. Perfluoro-2-azapropene gives low yields of the two isomeric 1:1 adducts perfluoro-(2,3-dimethyl-5-oxa-2,3-diazahexane) and perfluoro-(3,5-dimethyl-2-oxa-3

The synthesis and characterization of the new perfluorinated hypochlorite, undecafluoro-tert-pentyl hypochlorite, (C2F5)(F3C)2COCl, is reported. Its gas-phase infrared, UV/Vis and NMR spectra have been recorded and its spectroscopicproperties are discussed and compared with quantum-chemical predictions and those of other known perfluorinated hypochlorites such as RFOCl [RF = F3C, (F3C)3C, (C2F5)(F3C)2C]
据报道,新的全氟化次氯酸盐,十氟叔丁基戊基次氯酸盐(C 2 F 5)(F 3 C)2 COCl的合成和表征。已记录了其气相红外,UV / Vis和NMR光谱,并讨论了其光谱性质,并将其与量子化学预测以及其他已知的全氟化次氯酸盐如R F OCl [R F = F 3 C,(F 3 C)3 C,(C 2 F 5)(F 3 C)2C]。相应的次氯酸盐的低温光解也提供了合成途径,以其他方式难以获得的全氟化二烷基过氧化物R F OOR F。

Part of a study to synthesise via radical reactions perfluoroalkanes containing oxygen is illustrated with the olefin (CF3)2C:C(CF3)2. Photochemical oxidation of the olefin with short reaction time gives the ketones CF3.CO.CF(CF3)2 (48% yield), CF3.O.CF2.CO.CF3, CF3.O.CF2.CO.CF(CF3)2 and CF3.CO.CF3. The epoxide is a by-product not an intermediate in these reactions.

Abstract : AgF2 is a catalyst for the reaction, CO + F2 = CF2O and for subsequent changes in which COF2 reacts with fluorine to give CF3OF and CF3OOCF3. Cesium fluoride aids in the production of CF3OF but not CF3OOCF3 from fluorine and COF2. (Author)
A process is provided which yields derivatives of cephalosporins and penicillins. The process starts with 7-aminodecephalosporanic acid or 6-APA and reacts with a carbonyl containing compound to form a Schiff's base (imino) adduct. This latter compound is then treated with a defined reactant yielding a novel Schiff's base adduct having a side chain on the carbon adjacent to the imino-nitrogen. The amino moiety can be regenerated and further reacted to form end compounds which are active against both gram-positive and gram-negative bacteria.
