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 ...
