Syntheses of α,ω-di-1-anthrylpolyenes have been carried out by the Wittig reaction for information on the role of aromatic terminal groups on the electronic spectral regularity of α,ω-diarylpolyenes. The reaction of phosphoranes derived from 1-anthrylmethyl-, 3-(l-anthryl)propenyl-, and 5-(1-anthryl)-pentadienyltriphenylphosphonium bromides with 1-formylanthracene, 3-(1-anthyrl)propenal, 5-(1-anthryl)pentadienal
α,ω-di-1-anthrylpolyenes 的合成已通过 Wittig 反应进行,以获取有关芳族端基对 α,ω-二芳基多烯电子光谱规律的作用的信息。衍生自 1-蒽甲基-、3-(1-蒽基)丙烯基-和 5-(1-蒽基)-戊二烯基三苯基溴化物的正膦与 1-甲酰基蒽、3-(1-蒽基)丙烯醛、5-(1 -蒽基)戊二烯醛和粘胶醛通过正膦和醛部分的适当组合提供了一系列二-1-蒽基多烯(I1-6)。由于长波长区域的吸收带变宽,无法对电子光谱规律进行讨论。
