    摘要:
    The reductive dimerization of dithianylium ions, followed by oxidative fluorodesulfuration, opens a convenient access to a variety of 1,2-disubstituted tetrafluoroethylene derivatives.

The substituted quinoxalines as well as the pyrido[2,3-b]pyrazine (25) and the lumazines (27), (29), and (31) were all found to exist as completely dehydrated aromatic species. Depending on the reaction conditions, both the aromatic form (33) and the stable, neutral covalent dihydrate form (34) could be obtained from the reaction

    The synthesis of some 7,7-difluoro-7,8-dihydropterins and pterins with fluoroalkyl subsitutents at the 6 or 7 positions from fluorine-containing aliphatic precursors and suitably substituted pyrimidines is described. The fluorine-containing pterins were found to be very insoluble and also stable to nucleophiles and bases in dilute aqueous solution.

    Flash vacuum thermolysis of a variety of derivatives of tetrafluoroethene oligomers in the temperature range 450-600° at 20mm - 0.4mm Hg affords a number of unusual products. Thus, the pentamer (1) affords perfluoro 1,2,3- trimethyl cyclobutene (2), and perfluoro-2,3-dimethylpentadiene (3,) (4) as previously reported, but in much different ratios.

    Matrix studies on the photolytic reaction between ozone and hexafluoro-2-butyne have been performed at 11 K in argon and nitrogen matrices. The matrices were photolyzed with 640 and 642 nm light from a laser source, and with 254 nm light from a Hg arc lamp. The final products of the reaction are perfluorobutanedione and bis(trifluoromethyl)ketene. An intermediate species was also observed. It has been
