The reaction of transient [MeP-W(CO)5] with norbornene gives the two corresponding exo phosphiranes with W syn or anti to the norbornane bridge. The syn complex is selectively decomplexed by carbon monoxide at 120 °C under 50 bar. Both complexes are easily cleaved by Pd(OAc)2 at room temperature to give [MeP(OAc)2)]W(CO)5.
