8-bis-[1-(1′-phenylthio)ferrocenyl]naphthalene (1) and 8,8′-bis-[1-(1′-phenylthio)ferrocenyl]-1,1′-binaphthyl (2), respectively, were investigated. They were synthesized from the Suzuki coupling of 2,4,6-tris(1′-phenylthio-1-ferrocenyl)boroxin (3) with 1,8-diiodonaphthalene and 1,8-diiodo-1,1’-binaphthyl, respectively. Their structures were confirmed by single-crystal X-ray analyses. The two cyclopentadienyl
摘要1,8-双-[1-(1'-苯硫基)二茂铁基]萘(1)和8,8'-双-[1-(1'-苯硫基)二茂铁基]中二茂铁环的平行和垂直堆积分别研究了-1,1'-联萘(2)。它们是分别由1,4-二碘萘和1,8-二碘-1,1'-联萘的2,4,6-三(1'-苯硫基-1-二茂铁基)硼氧烷(3)的Suzuki偶联合成的。通过单晶X射线分析证实了它们的结构。两个分别为1的二茂铁Fe(1)和Fe(2)的两个环戊二烯基(Cp)环(C9C13和C19C23)不平行,但相距21.3°。这两个Cp环的质心之间的距离为3.336A。两个二茂铁Fe(1)和Fe(2)的两个Cp环(C9C13和C9'C13')不是垂直的,而是二面角为49.9°,且这两个Cp环的两个质心之间的距离为5.255A。在二氯甲烷溶液中1和2的电化学行为表明,它们可逆地经历了以二茂铁为中心的单电子氧化,生成相应的指示。相对于2,两个阳极过程之间
