Original Abstract

The donor-acceptor complexes Et2O.SeO3 and (Me2O)2.SeO3 can be obtained as primary products by the reactions of selenium trioxide with dimethyl ether (Me2O) and diethyl ether (Et2O). The crystal and molecular structure of both complexes, which are stable below their melting points only, was determined by X ray structure analysis. Pairs of molecules Et2O.SeO3 form dimers due to two weak intermolecular Se...O contacts. No intermolecular interactions were observed in (Me2O)2.SeO3. Trigonal bipyramidal coordination around SeVI atoms in the latter complex is almost undistorted. Conversion of the adducts to dialkylesters of diselenic and selenic acid in the liquid phase was monitored by Raman, 1H- and 77Se-NMR spectroscopy.
