Preparation and Characterisation of Tantalum(V) β-Diketonates (Part II)
1983
Abstract Reactions of tantalum pentaethoxide with p-haloarylsubstituted β-diketones as well as 2-thenoyltrifluoroacetone were carried out using different molar ratios. Compounds of the type [Ta(OEt)5-n(L)n], (where L = p-fluoro-, p-chloro-, p-bromobenzoylacetone and 2-thenoyltrifluoroacetone; n = 1, 2 or 3), have been isolated and characterised by elemental analysis, molecular weight determinations and spectral studies like i.r., and 1H n.m.r. Alcoholysis reactions with tertiary butanol were also carried out.
