Base-stabilized phosphinidene boranes via silylium-ion abstraction

Research output: Contribution to journalArticlepeer-review


We report the preparation of NHC-stabilized compounds containing P=B double bonds. The reaction of the highly functionalized phosphinoborane Mes*(SiMe3)P-B(Cl)Cp* with Lewis bases allows access to base-stabilized phosphinidene boranes, Mes*P=B(L)Cp* (L = DMAP, NHC) via Me3SiCl elimination. The formation of these species is shown to proceed via transient boryl-phosphide anions generated by Me3Si abstraction.
