Isolable chloro[(thio)alkoxy]triorganylphosphoniumchlorides RR2'P-X-CH2R"] + Cl- are synthesized by reaction of oxiranes (2-5) (oxetane (6), thiiranes (18a-c)) with dichloro-phosphoranes (1a-f). Structure and stability are discussed. Thermal Arbusov-rearrange-ment yields vicinal di-resp. trihalo-alkanes and phosphanoxides. The structures are confirmed by 31P{1H} and 13C{1H} NMR data.
