derivatives containing an isocyanate group react readily with the activated carbonyl compounds to give a variety of difficultly accessible P-heterocycles: spirophosphoranes [1], diazadiphosphetidines, 1,3,2-dioxaphosphepines [2]. Thus, the reactions involving perfluoro-para-quinone [3] and para-substituted arylcarbonylphosphonates [4] result in the substituted phosphabicyclononanes containing phosphorus–oxygen
含有异氰酸酯基团的功能取代的 P(III) 衍生物很容易与活化的羰基化合物反应,生成各种难以获得的 P-杂环:螺正膦 [1]、二氮杂二膦、1,3,2-二氧杂膦 [2]。因此,涉及全氟对醌 [3] 和对位取代的芳基羰基膦酸酯 [4] 的反应会产生含有磷-氧、磷-氮和磷-碳键的取代磷杂双环壬烷。
