Abstract
The reactions of niobium pentaethoxide with acetylacetone, benzoylacetone and of tantalum pentaethoxide with acetylacetone have been studied and derivatives of the type M(OEt)x(lig)5-x (where M = Nb or Ta; lig = acetylacetone or benzoylacetone; x = 4, 3 or 2) have been isolated. These derivatives interchange their ethoxy groups with tertiary butoxy groups on refluxing with tert.-butyl alcohol. The molecular weights of β-diketonate as well as β-ketoester derivatives of niobium and tantalum have been determined ebullioscopically in benzene.
