## Abstract The oxidation of 1,5‐dimethyl‐2,4‐bis(diethylamino)‐1,5‐diaza‐2,4‐diphosphorinan‐6‐one __5__ with tetrachloroorthobenzoquinone (TOB) leads to the formation of the spirophosphorane __9__, which is unstable and undergoes an unusual spontaneous rearrangement into the isomeric methylenephos
