synthesised by reaction of hexachlorobenzene with an excess of the sodium salt of β-mercaptonaphthalene in 1,3-dimethyl-2-imidazolidinone (DMEU) as solvent; other hexakis (arylthio)- benzenes, hexakis(phenoxy) benzene (IV), and hexakis (phenylseleno) benzene (V) were prepared analogously from hexahalobenzenes, HMPA being used as solvent in the last case. An X-ray analysis of the channel-type adduct of (III) with
标题主体分子(Ⅲ)是通过六氯苯与过量的β-巯基萘的钠盐在1,3-二甲基-2-咪唑啉酮(DMEU)中的溶剂反应而合成的。其他六(芳硫基)苯,六(苯氧基)苯(IV)和六(苯硒基)苯(V)也由六卤代苯类似地制备,在后一种情况下,HMPA用作溶剂。用1,4-二恶烷作为客体的(III)通道型加合物的X射线分析揭示了独特的主体构象,其中侧链不交替位于中央苯环平面的上方和下方。
