The facile synthesis of [n](2,4)pyridinophane ring system (n = 9–6) was accomplished by the reaction of N-(1-phenylvinyl)iminophosphorane with cyclic α, β-unsaturated ketones. The chain flipping was studied by 1H NMR spectra at various temperatures.
[n](2,4)吡啶环体系(n = 9–6)的简便合成是通过N-(1-苯基乙烯基)亚氨基正膦与环状α,β-不饱和酮的反应完成的。通过在不同温度下的1 H NMR光谱研究了链翻转。
