  • Heterogeneously catalyzed process for cross coupling alkenyl halides with boronic acids
    Publication number: 20020045775
    Abstract: The present invention relates to a process wherein heterogeneous finely dispersed palladium catalysts are used for cross coupling of alkenyl halides and boronic acids in the presence of base in an aprotic solvent to produce aryl- or heteroaryl-olefin compounds. The process provides for use with either electron-withdrawing or electron-donating substituents for cross coupling of alkyl halides with boronic acids.
