GRAPHICAL ABSTRACT Abstract The preparation of four-memberedphosphorus(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
