EFFECTIVE BIARYL COMPOUND SYNTHESIS USING CROSS-COUPLING REACTION WITH NICKEL-COMPLEXES COORDINATED BY DIAMINOPHOSPHINE LIGANDS

The cross-coupling reaction of aryl halides and aryl Grignard reagents was effectively catalyzed by the diaminophosphine complex catalysts a nd the reaction was much faster than that catalyzed by aminophosphine complexes and the nickel complexes were more active than palladium com plexes. Various biaryl compounds were easily prepared by the reaction with nickel diaminophosphine catalysts.
