azaphosphinines is reported. The synthesis of 1,3‐ and 1,4‐aza‐λ3‐phosphinines as well as 1,2,4‐diaza‐λ3‐phosphinines by inverse‐electron‐demand hetero‐Diels–Alder reactions of sodium 2‐phosphaethynolate [NaOCP] with triazines and tetrazines is studied. In the case of 1,2,4‐triazines a hetero‐D.A. reaction was developed, which relies on a new directing‐group approach based on the complexation of sodium to form
在本文中,报道了一种直接的合成氮杂膦的合成方法。的1,3-和1,4-氮杂λ合成3 -phosphinines以及1,2,4-二氮杂- λ 3 -phosphinines由钠2- phosphaethynolate的逆电子需求杂狄尔斯-阿尔德反应研究了三嗪和四嗪[NaOCP]。在1,2,4-三嗪的情况下,开发了一个异质DA反应,该反应依赖于基于钠络合形成离子Do→Na-OCP系链的新的导向基团方法。为氮杂λ的第一X射线表征数据3 -phosphinines以及第一phosphinine三氟甲磺酸酯被呈现。
