Abstract:
The present invention relates to a preparation of β-γ ene carboxylic or ketone derivatives, which may also have particular requirement on the configuration of the carbon-carbon double bond. The method requires a thermal treatment of α-β unsaturated malonate or acetylacetonate derivatives in the presents of at least one carboxylic acid and at least one alkaline, alkaline-earth or lanthanide halide or carboxylates.
