摘要: The reductive functionalization of carbon dioxide into high value organics was accomplished via the coupling with monoxide and ethylene/propylene at a zerovalent nickel species bearing 2-((di-t-butylphosphino)methyl)pyridine ligand (PN). An initial oxidative between dioxide, olefin, (PN)Ni(1,5-cyclooctadiene) afforded five-membered nickelacycle lactone species, which were produced regioselective 1,2-coupling in case propylene. propylene derived isolated characterized by X-ray diffraction. Addition monoxide, or combination diethyl zinc to complexes cyclic anhydrides 1,4-ketoacids, respectively, moderate yields. primary organometallic product transformation (PN)Ni(CO)2.
