  obtained in increased yields. Similarly, the treatment of diphenylcyclopropenone with sodium amalgam in isopropyl alcohol - acetic acid gave tetraphenyl-p-benzoquinone and tetraphenylpyrocatechol in 4% and 20% yields respectively. These results suggest that diphenylcyclopropenone gives pinacol, 1, l′-dihydroxy-2, 2′, 3, 3′-tetraphenyl-l, l′-bi-cyclopropenyl, under the reaction conditions, but the pinacol

  二苯基环丙烯酮与环戊二烯基溴化镁的反应没有得到预期的叔甲醇，但导致形成四苯基环戊二烯酮、四苯基对苯醌和四苯基焦儿茶酚，产率分别为 1%、2% 和 8%。当二苯基环丙烯酮用金属镁和碘的混合物处理时，以增加的产率获得相同的产物。类似地，在异丙醇-乙酸中用钠汞齐处理二苯基环丙烯酮，分别以 4% 和 20% 的产率得到四苯基对苯醌和四苯基焦儿茶酚。这些结果表明，在反应条件下，二苯基环丙烯酮生成频哪醇，1，l'-二羟基-2, 2', 3, 3'-四苯基-l, l'-双环丙烯基，

  To provide a fluorinated aromatic polymer having excellent heat resistance and a low relative permittivity; and an insulating film for electronic devices and an insulating film for multilayered wiring boards, which are made of the polymer. A fluorinated aromatic polymer which contains two or more crosslinkable functional groups (A) per molecule and has a number average molecular weight of from 1×10 3 to 5×10 5 and an ether linkage and which is produced by e.g. a method in which a branched fluorinated aromatic compound (B) represented by the formula 1 and a compound (Y1) having a crosslinkable functional group (A) and a phenolic hydroxyl group, are subjected to a condensation reaction in the presence of a HF-removing agent: 1

  The palladium-catalyzed Suzuki-Miyaura coupling reaction of tetrabromo-p-benzoquinone and 2,3-dibromonaphthoquinone provide a convenient approach to tetraaryl-p-benzoquinones and 2,3-diarylnaphthoquinones. Suzuki-Miyaura of tetrabromo-1,4-phenylene bis(trifluoromethanesulfonate) and of 2,3-dibromonaphthalene-1,4-diyl bis(trifluoromethanesulfonate) resulted in the formation of the same type of quinone products instead of the expected benzene and naphthalene derivatives.
