the indanonophanes 25–28 by Wittig-Horner chain elongation, hydrogenation, saponification and Friedel-Crafts ring closure. Whereas 25–27 may be reduced easily to the [2,2]indenophanes 29–31, the pseudo-geminal diketone 28 affords ether 35 and monoketone 39 on lithium aluminium hydride reduction followed by dehydration. The mechanisms of these processes are discussed. The molecular structures of the mono-iron
双-甲酰基[2.2] paracyclophanes 21 - 24,容易地通过丙炔醛(环加成获得的18),以1,2,4,5- hexatetraene(17),被转换为indanonophanes 25 - 28通过维蒂希-霍纳链伸长,加氢,皂化和Friedel-Crafts闭环。而25 - 27可以容易地降低到[2,2] indenophanes 29 - 31,该伪-geminal二酮28次,得到醚35和单酮39氢化铝锂还原,然后脱水。讨论了这些过程的机制。由X的16阴离子制备的单铁络合物6和40的分子结构已通过X射线结构分析确定。
