Abstract

In this work the reaction of the unsaturated pentadieneoic- and hexadieneoic acids and their derivatives with zerovalent nickel and platinum is examined. This reaction shows product selectivity depending on the coligand and the metal centre. With [Ni(COD)_2] as metal(0)-precursor and sterically demanding phosphines as coligands the reaction results in the formation of nickelacyclic #eta#"3-allyl-carboxylates, where the carboxyl-group coordinates monodentate after migration of the acidic proton to the beta-carbon of the acid. The nickel-allylcarboxylates where characterised by X-ray-diffraction analysis, NMR-,IR-, UV-spectroscopy and by cyclovoltammographie.
