Nucleophilic aromatic substitution of all the chlorine atoms in 1,3,5,7,9-pentachlorocorannulene and in decachlorocorannulene by sodium alkanethiolates gives 1,3,5,7,9-pentakis(1-alkylthio)corannulenes, C20H5(SR)5, and decakis(1-alkylthio)corannulenes, C20(SR)10, respectively, with arms of varying lengths attached around the perimeter (R = n-propyl, n-hexyl, and n-dodecyl). The corresponding reaction of decachlorocorannulene with ortho-C6H4(SNa)2 gives pentakis(1,4-benzodithiino)corannulene, a molecular bowl with 6 Å flaps on all five sides. Such compounds represent attractive candidates for the formation of discotic liquid crystals and/or supramolecular complexes with fullerenes and other convex guests.
1,3,5,7,9-五氯核甾烯和十氯核甾烯中的所有氯原子与烷基硫醇钠发生亲核芳香取代反应,分别得到1,3,5,7,9-五(1-烷基硫)核甾烯,C20H5(SR)5,以及十(1-烷基硫)核甾烯,C20(SR)10,周边附有不同长度的侧链(R = n-丙基,n-己基和n-十二烷基)。十氯核甾烯与邻位-C6H4(SNa)2的相应反应生成五(1,4-苯并二硫)的核甾烯,这是一种在所有五个侧面都有6 Å 翼片的分子碗。这些化合物是形成盘形液晶和/或与富勒烯及其他凸客体的超分子复合物的有吸引力的候选者。
