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.
Abstract (in Czech)
DA-komplexy Et2O.SeO3 a (Me2O)2.SeO3 lze získat jako primární produkty reakcí oxidu selenového s Me2O resp. Et2O. Krystalová a molekulová struktura obou komplexů, které jsou stálé pouze při teplotách nižších než je jejich bod tání, byla stanovena rentgenograficky. Dvojice molekul Et2O.SeO3 tvoří dimery v důsledku dvou slabých intermolekulárních Se...O kontaktů. V (Me2O)2.SeO3 žádné intermolekulární kontakty nebyly zjištěny, trigonálně bipyramidální koordinace kolem SeVI v něm není porušena. Konverze aduktů na dialkylestery kyselin diselenové a selenové v kapalné fázi byla monitorována Ramanovou, 1H- a 77Se-NMR spektroskopií.
