YTTRIUM, DYSPROSIUM, AND YTTERBIUM ALKOXIDES.
Abstract
Isopropoxides of yttrium, dysprosium, and ytterbium have been prepared by reacting the metals with isopropyl alcohol using mercuric chloride as a catalyst. The reactants were refluxed for 24 hours at 82 C, and the isopropoxides recrystallized from isopropyl alcohol. The use of stoichiometric amounts of mercuric chloride resulted in chloride contamination and alkene-alkoxide formation. Heavier alkoxides were made by an alcoholysis reaction of the isopropoxides with the appropriate higher boiling alcohol in benzene. Compounds prepared by alcoholysis methods included the 2-pentoxides of yttrium, dysprosium, and ytterbium and yttrium tertiary-butoxide, 3-methyl-2-butoxide, 2-hexoxide, 3-ethyl-3-pentoxide, 3-hexoxide, 2-ethyl-1-hexoxide, and phenoxide. All the alkoxides were either solids or semisolids which sublimed or decomposed on heating at 200 C or higher. Thermal and hydrolytic decomposition was quantitative to the oxides. Some infrared spectra and data are presented. (Author)
