A COORDINATION MODEL AS AN ALTERNATIVE TO THE SOLVENT SYSTEM CONCEPT IN SOME OXYCHLORIDE SOLVENTS. I. SIMILARITY IN THE BEHAVIOR OF PHOSPHORUS OXYCHLORIDE AND TRIETHYL PHOSPHATE AS NON-AQUEOUS SOLVENTS
The solution behavior of anhydrous ferric chloride in triethyl phosphate STAPO(OEt)sub 3/! is shown to be very similar to the reported behavior of ferric chloride in phosphorus oxychloride. Spectral investigations demonstrate that the tetrachloroferrate (III) ion, STAFeCl/sub 4/!- on dissolution of ferric chloride in triethyl phosphate is a direct proof that ioniza-. tion of some FeCl/sub 3/ produces a cationic iron(III) species. This is interpreted as strong support for using a similar Lewis acid-base mechanism to explain the data in both POCl/sub 3/ and PO(OEt)/sub 3/. It is not necessary to obtain a chloride ion from the solvent POCl/sub 3/ to form STAFeCl/sub 4/!/sup -/. The equilibria shown are proposed to explain the behavior of ferric chloride in triethyl phosphate and to serve as an alternative to the solvent system explanation for phosphorus oxychloride solutions.
