Some fulvalenoids containing 1,3-dithiepin counterpart (5a), (5b), and (5c) have been synthesized through the reaction of 2-trimethylsilyl-1,3-dithiepinide ion (6) with di-tert-butyl-cyclopropenone, 2,3;6,7-dibenzotropone, and fluorenone, respectively. Comparison of the 1H-NMR spectra of these fulvalenes indicated the electron accepting ability of the 1,3-dithiepin moiety.
通过 2-trimethylsilyl-1,3-dithiepinide 离子 (6) 与二叔丁基环丙烯酮的反应合成了一些含有 1,3-dithiepin 对应物 (5a)、(5b) 和 (5c) 的富瓦烯类化合物,分别为 2,3;6,7-二苯甲酮和芴酮。这些富瓦烯的 1H-NMR 谱的比较表明 1,3-二硫杂环庚烷部分的电子接受能力。
