ResumoPalladium bis(hexafluoroacetylacetonate), Pd(F6acac)2, forms a strongly bound surface complex on alumina. It is analogous to Lewis acid-base complexes such as Pd(F6acac)2[(CH3)2NH]2 which are formed with molecular donors. Heating the supported Pd(F6acac)2 with hydrocarbons such as benzene and propene leads to cracking of the hydrocarbon and reduction of the surface complex to palladium metal. The F6acac ligand is released as hexafluoroacetylacetone which remains attached to the alumina. On prolonged standing or on heating, the hexafluoroacetylacetone is degraded with an accompanying shift of fluorine from carbon to aluminum.
