Abstract

Robust acenaphthoimidazol-ylidene palladium complexes with varying bulky substituted groups exhibited extremely high catalytic activity toward Negishi cross-coupling of alkylzinc reagents with a wide range of (hetero)aryl halides under mild reaction conditions within short reaction times. Besides a great number of bromoarenes, various less expensive and inactive (hetero)aryl chlorides were coupled successfully with alkyl- and arylzinc reagents.
