A Diglyme Adduct of Tin(IV) Chloride Formed on Drying Aromatic Solvents by the Benzophenone Ketyl/Potassium Metal Method

Abstract
Use of diglyme (diethyleneglycoldimethylether) for solubilization in the benzophenone ketyl/potassium metal method for drying and deoxygenating aromatic solvents can result in contamination of the distilled solvent with subsequent formation of adducts with Lewis acids. The diglyme adduct of tin(IV) chloride is isolated, and the magnitude of its tin-119m Mòssbauer Quadrupole Splitting interpreted in terms of its structure.
