Abstract
Abstract Central carbon-bonded acetylacetonato complexes of platinum(II) and palladium(II) [M(acac)(γ-acac)PPh 3 ], I (M = Pt and Pd), reacted with β-dicarbonyl compounds (Hdik) to give three types of complexes according to the nature of the β-dicarbonyl compounds employed; dimethyl malonate and methyl and ethyl acetoacetates yielded [M(acac)(γ-dik)PPhP 3 ], II, whereas dibenzoylmethane afforded [M(dik)(γ-acac)PPh 3 ], IV, exclusively. The reaction of benzoylacetone with I afforded a mixture of [M(dik)(γ-dik)PPh 3 ], III, and IV. The selectivity of the reaction seems to be correlated with the enol- or keto-favoring character of the respective β-dicarbonyl compounds.
