ABSTRACT:
A method for the preparation of biaryl compounds is disclosed which comprises contacting an aryl halide with a tertiary-alkyl organometallic reagent (or the precursor components thereof) in the presence of a catalyst comprising a nickel compound and a coordinating ligand under conditions suitable for the formation of biaryl compound.
In an alternative embodiment of the present invention, nickel(0) compounds are prepared from nickel(II) compounds by contacting a nickel(II) compound with a combination of an organophosphine and a bidentate nitrogen-containing coordinating ligand, and a tertiary-alkyl organometallic reagent (or the precursor components thereof) in an aprotic, non-polar, ether-containing solvent system for a time and under conditions suitable for the formation of nickel(0) compound.
