| Abstract: | Several new mononuclear complexes of Pd(II) have been prepared from perfluorobutyl substituted 1,3,5-triketones (containing linear and carbocycle backbones) and perfluoroheptanoyl cyclohexanone. 1,3-Diketones formed a mixture of trans- and cis-forms, whereas 1,3,5-triketones gave trans-complexes exclusively. The enolization of the non-bonded carbonyls in this case depends on the nature of substituents at positions 2 and 4 of the 1,3,5-triketone moiety. The molecular structure of one triketonate complex was confirmed by X-ray single crystal investigation. |
