Abstract
A process for preparing palladium(II)acetylacetonate having a low content in organically linked chlorine by reaction of acetylacetone with palladium dichloride or the complex tetrachloropalladinates derived therefrom, which comprises dissolving the starting palladium dichloride compound in hydrochloric acid, adding to the solution at least the stoichiometric amount of acetylacetone, stirring until the solution has become clear, adjusting the solution to a pH-value between 7 and 8 by drop-wise addition of an aqueous alkali hydroxide solution, separating the precipitated palladium(II)acetylacetonate from the solution, rinsing the palladium(II)acetylacetonate with water to free it from inorganic chloride, and drying. The products made by the process of the invention are effective catalysts in a variety of synthetic processes e.g. oxosyntheses, oligo and polymerizations, vinylization of aromatics and so on.
