    Substituent effects on the chemical shifts of the bridge protons of benzonorbornenes
    摘要:
    在一系列6-取代苯基诺邻二环烯和苯基诺邻二烯中,对C9桥上质子的化学位移进行了取代效应的研究,以及对5-取代2-茚醇中C2质子的影响。这些效应与修正的Hammett关系τR - τH = ρ (σm + σp)/2呈线性相关。在苯基诺邻二烯中,从反式C9质子获得的ρ值略微但显着大于从相应的顺式质子获得的值,而从顺-9-苯基诺邻醇和茚醇中获得的ρ值之间没有显著差异。较大的ρanti值可以解释为苯环的π-电子体系与桥碳的轨道体系之间的立体特异性电子相互作用。此外,结果表明上述修正的Hammett关系通常与苯环环烯和类似化合物的脂肪成分的取代效应具有良好的一致性。
