DIENCARBONSAEUREN AUS 1,3-DIENEN UND CO2 DURCH C-C-VERKNUEPFUNG AN NICKEL(0)

Article abstract of DOI:10.1016/0022-328X(84)80144-8

(Lig)Ni⁰ systems react with 1,3-dienes in the presence of CO2 to give nickela carboxylates.The influence of ligands and temperature on the regioselectivity of the C-C bond formation is elucidated.In some cases the nickela carboxylates undergo reductive elimination under the influence of maleic anhydride, and the coupled diene/CO2 moiety rearranges to give the diene carboxylic acid.A possible reaction sequence is discussed.
