  • Dehydroannulenes. III. Synthesis and Properties of 1,5,10,14-Tetra-<i>tert</i>-butyl-6,8,15,17-tetrakisdehydro[18]annulene
    作者:Sachiyo Tomita、Masazumi Nakagawa
    DOI:10.1246/bcsj.49.302
    日期:1976.1
    In order to find out substituent groups which provide stability and solubility to tetrakisdehydro[18]annulene system without appreciable electronic interaction with the annulene ring, the synthesis of 1,5,10,14-tetra-tert-butyl-6,8,15,17-tetrakisdehydro[18]annulene (VIII) has been catrried out starting from 3-tert-butyl-2-penten-4-ynal (III). It was found that the tetra-tert-butyl derivative (VIII) is strongly diatropic, and more stable and much more soluble than tetramethyl-, dimethyl-, diphenyl-, and tetraphenyl-analogues. The electronic spectrum of tetra-tert-butyl derivative (VIII) was found to be closely related with that of tetramethyltetrakisdehydro[18]annulene indicating a minor electronic perturbation of tert-butyl groups on the annulene ring.
    为了找出在不显著影响富烯环电子相互作用的条件下,能够为四脱氢[18]富烯体系提供稳定性和溶解性的取代基团,从3-叔丁基-2-戊烯-4-炔醛(III)出发,进行了1,5,10,14-四叔丁基-6,8,15,17-四脱氢[18]富烯(VIII)的合成。研究发现,四叔丁基衍生物(VIII)具有强烈的抗磁环流性质,比四甲基、二甲基、二苯基和四苯基类似物更稳定且溶解度更高。四叔丁基衍生物(VIII)的电子光谱与四甲基四脱氢[18]富烯的光谱密切相关,这表明叔丁基对富烯环的电子扰动较小。

    Tetra-t-butylhexakisdehydro[18]annuleno[26]annulenedione, a key substance for the synthesis of tetra-t-butyloctakisdehydro[18]annuleno[18]annuleno[18]annulene has been synthesized. Formation of di-t-butyldifurotrisdehydro[18]annulene was observed on heating a solution of diformylmethylene derivative of the tetrakisdehydro[18]annulene.

    introduction of substituents, the syntheses of 1,8-bisdehydro[14]- and 6,8,15,17-tetrakisdehydro[18]annulenes bearing p-substituted phenyl group(s) have been performed. The examination of their 1H NMR spectra indicates that the low field shift of NMR signals can be regarded as a superposition of three effects, i.e., 1) decrease of ring current in annulene nucleus by perturbation of substituent group(s), 2) Deshielding
    为了获得'乙炔-枯草烯'-脱氢环烯在取代基引入时1H NMR信号低场位移的原因,合成了1,8-双脱氢[14]-和6,8,15,17-已经进行了带有对取代苯基的四脱氢 [18] 环烯。对其 1H NMR 谱的检查表明,NMR 信号的低场位移可被视为三种效应的叠加,即 1) 取代基的扰动降低了轮烯核中的环电流,2) 去屏蔽效应芳基取代基中环电流的影响施加在轮烯质子上,和 3) 苯基中的 p 取代基传递到轮烯环上的电子效应。

    Two position isomers of di-t-butyl-diphenyl-1,8-bisdehydro[14]annulene corresponding to o- and m-isomers of terphenyl have been prepared by a stepwise reaction sequence, and their physical properties were compared with those of 3,10-di-t-butyl-7,14-diphenyl-1,8-bisdehydro[14]annulene which corresponds to the p-isomer of terphenyl. The marked difference in electronic spectra between o-, m-, and p-isomers

    日期:1974.8.5
    Two position isomers of di-t-butyl-diphenyldidehydro[14]annulene have been prepared according to a stepwise sequence of reactions and their physical properties were compared with those of another position isomer, 3,10-di-t-butyl-7,14-diphenyl-1,8-didehydro[14]annulene. The synthesis of 3, 10-di-t-butyl-6,13-dimethoxy-7,14-diphenyl-1,8-didehydro[14]annulene has been performed. The introduction of methoxy groups causes a hypsochromic shift with hypochromism and a bathochromic shift with strong hyperchromism of medium and longest wavelength bands of the electronic spectrum, respectively.
