Abstract

Reactions of niobium and tantalum penta-ethoxides with n- and isopropanols, n-, sec.- and tert.-butanols and tert.-pentanol have been studied. In order to make a comparative study of the reactivities of primary, sec.- and tert.-alcohols, the reactions of niobium and tantalum penta-alkoxides (methoxides, ethoxides and isopropoxides) with tert.-butanol, and niobium and tantalum penta-tert.-butoxides with alcohols (methanol, ethanol and isopropanol) have been studied and products of the type M(OBut)(OR)4 (where M is niobium or tantalum) obtained. However, the reactions of penta-methoxides with tert.-butanol yield finally M(OBut)1.5(OMe)3.5. The identity of these mixed alkoxides has been established by distilling or subliming them under reduced pressure. Molecular weights of these mixed alkoxides were determined ebullioscopically in benzene.
