Abstract

1,2-Oxaphosphetanes are well established intermediate species in the Wittig reaction. Initially, isolable 1,2-oxaphosphetanes represented a source of structural information aimed at supporting mechanistic studies. The evolution of the subject allows the envisaging of stable 1,2-oxaphosphetanes as precursors for the stereoselective formation of olefins.

Keywords: oxaphosphetanes, olefination, wittig, spiro-heterocycles, phosphorus ylides, phosphazenes
