  • [24]Pentaphyrin(2.1.1.1.1): A Strongly Antiaromatic Pentaphyrin
    作者:Tomoki Yoneda、Tyuji Hoshino、Saburo Neya

    日期:2017.10.6
    [24]Pentaphyrin(2.1.1.1.1) 1 was synthesized by dehydrogenation of dihydropentaphyrin(2.1.1.1.1) 2 as the first example of vinylogous pentaphyrin. Pentaphyrin 1 takes a roughly planar structure and shows strong antiaromatic character, reflecting a 24π-conjugated circuit. In spite of the antiaromatic character and the relatively small circuit, 1 is stable under ambient conditions.
    [24] Pentaphyrin(2.1.1.1.1)1由dihydropentaphyrin(2.1.1.1.1)的脱氢来合成2为插烯pentaphyrin的第一个例子。pentphyrin 1具有大致平面的结构,并显示出很强的抗芳烃特性,反映了24π共轭电路。尽管具有抗芳烃特性和相对较小的电路,但1在环境条件下仍是稳定的。

    molecular-ion peak in high-resolution mass spectrometry, 1D and 2D NMR spectroscopy, and X-ray structure obtained for one of the oxapentaphyrin(2.1.1.1.1) macrocycles. The crystal structure and NMR studies indicated that the heterocyclic ring, such as furan in oxapentaphyrins(2.1.1.1.1) and thiophene in thiapentaphyrins(2.1.1.1.1), was inverted. In absorption spectra, the macrocycles showed one sharp band
