Synthesis and properties of four-membered phosphorus heterocycles-2-Fluoro-1,2λ5-Oxaphosphetanes

(Graphical 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 1, 13C, and 31 NMR spectra. The fluoro-1,2λ5-oxaphosphetanes may be easily converted to various alkenylphosphonates: allyl- or vinylphosphonates. This reaction represents a good method for the preparation of phosphorylated alkenes.

TRANFORMATION DES 2-FLUORO-1,2λ5-OXAPHOSPHETANES EN ALLYLPHOSPHONATES

P-Fluoro-ylids 1 adds aldehydes and ketones to produce 2-fluorooxaphosphetanes 2 that convert, depending upon the nature of substituents in C-3 and C-4 atoms into allylphosphonates or vinylphosphonates.
