Description: This article discusses the consequences of electronic effects. 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.
