Abstract: Oxygen atom transfers involving metal-oxo functionalities are central to many biological transformations, prominent in applications to organic synthesis, and of increasing importance in inorganic systems as synthetic tools, objectives in biomimicry, and targets of fundamental studies. As a synthetic route to (silox)₃WN (4, silox = ᵗBu₃SiO), the deoxygenation of (silox)₃WNO (2) by (silox)₃Ta (1-Ta) was attempted without success, despite ample precedent in cleavages of epoxides, N₂O, NO, CO₂, and CO. A comparison study involving sources of M(silox)₃ (1-M; M = V, Nb, Ta) revealed that features of deoxygenations of 2 and R₃PO) (R = Me, Ph, ᵗBu) are the consequences of electronic effects enforced by a limiting steric environment.
