Several derivatives of bowl-shaped tribenzotriquinacenes with Lewis-acidic atoms are reported. Six acetylene functions were attached to the benzene rings and these can carry six SnMe or SiMe groups. Direct functionalization of the benzhydrylic positions with the silyl groups of tribenzotriquinacene in in situ Grignard reactions is reported. Such silyl groups carry various substituents; the Si-H functional species were shown to be convertible into Si-F, Si-Cl and Si-Br functional compounds. The benzhydrylic positions were also substituted by allyl and p-iodo-phenyl functions; the first were further functionalized with a variety of silyl groups (SiCl, SiMeCl, SiF, SiMeF), the latter with trimethylsilylethynyl substituents and this product desilylated to a tris-(p-ethynyl-phenyl) tribenzotriquinacene. The complexation of a SbCl unit by a tribenzotriquinacene derivative with a new chelating tris-arene binding motif of the antimony atom is also reported.
报道了几种带有路易斯酸性原子的碗状三苯并三喹啉衍生物。六个乙炔官能团连接到苯环上，这些官能团可以携带六个 SnMe 或 SiMe 基团。报道了在原位格氏反应中，三苯并三喹啉的甲硅烷基对二苯甲基位置的直接官能化。此类甲硅烷基带有各种取代基；已表明 Si-H 官能物种可转化为 Si-F、Si-Cl 和 Si-Br 官能化合物。二苯甲基位置也被烯丙基和对碘苯基官能团取代；前者用各种甲硅烷基（SiCl、SiMeCl、SiF、SiMeF）进一步官能化，后者用三甲基硅乙炔基取代基官能化，该产物脱硅生成三（对乙炔基苯基）三苯并三喹啉。还报道了具有新的锑原子螯合三芳烃结合基序的三苯并三喹啉衍生物对 SbCl 单元的络合作用。
