A TWO STEP PROCEDURE AS IMPROVED ALTERNATIVE TO THE CYCLOCARBONYLATION OF ALLYL HALIDES AND ACETYLENE DERIVATIVES MEDIATED BY Ni(CO)4

Article abstract of DOI:10.1016/S0040-4039(00)82199-1

The addition of allyl halides to acetylenic derivatives catalyzed by Pd(II) complexes, such as bis-acetonitrile palladium(II) bromide, followed by cyclocarbonylation of the resulting cis adducts with Ni(CO)4 in CH3CN containing precise amounts of CH3OH an
