phenanthrylpentadienyltriphenylphosphonium bromides and l,4-bis(triphenylphosphonium)-2-butene dibromide were converted into phosphoranes (V, V′, V″, VI, VI′, VII″, IX, IX′, IX″, VII) by a reaction with phenyllithium. The reaction of carbonyl components with phosphoranes with a proper combination yielded diphenanthrylpolyenes (In, In′, In″). 2- and 3-Phenanthryl derivatives (In and In′) exhibited electronic
α,ω-二(2-菲基)-、二(3-菲基)-和二(9-菲基)多烯(In, In', and In", n=1-6)的合成描述了 Wittig 反应。甲酰基菲 (II, II', II")、菲基丙烯醛 (III', III")、菲基戊二烯醛 (IV, IV', IV") 和粘酮醛 (VIII) 用作反应中的羰基组分。菲基甲基-、菲基丙烯基-和菲基戊二烯基三苯基溴化鏻和l,4-双(三苯基鏻)-2-丁烯二溴化物被转化为正膦(V, V', V", VI, VI', VII", IX, IX', IX" , VII) 与苯基锂反应。羰基组分与正膦以适当的组合反应产生二菲基多烯(In、In'、In”)。2- 和 3- 菲基衍生物(In 和 In')表现出具有明确振动精细结构的电子光谱,而 9-菲基衍生物 (In") 显示出宽且无结构的吸收曲线。发现 I 的最长波长最大值 (λmax) 的图...
