GRAPHICAL ABSTRACT Abstract The preparation of four-membered phosphorus(V)-heterocycles, 2-fluoro-1,2λ5-oxaphosphetanes, by reaction of P-fluoroylides with carbonyl compounds is described. The reaction is stereoselective and leads preferentially to the formation of threo-1,2λ5-oxaphosphetanes. Oxaphosphetanes were isolated as individual compounds and their structures were confirmed by 1Н, 13C, and
图形摘要 摘要 描述了通过 P-氟代与羰基化合物反应制备四元磷 (V)-杂环、2-氟-1,2λ5-氧杂膦烷。该反应是立体选择性的,并优先导致形成 threo-1,2λ5-oxaphosphetanes。Oxaphosphetanes 作为单独的化合物被分离出来,它们的结构通过 1Н、13C 和 31Р NMR 光谱证实。氟-1,2λ5-氧杂膦可以很容易地转化为各种链烯基膦酸酯:烯丙基或乙烯基膦酸酯。该反应是制备磷酸化烯烃的好方法。
