摘要
Arylketones were formed from the Cr(CO)(3) complex of (trialkylstannyl)benzene or chlorobenzene by a palladium-catalyzed cross-coupling reaction in the absence of external CO. The Cr(CO)(3) moiety provides the required CO predominantly by an intramolecular mechanism. Products due to a direct coupling reaction were also observed. The influence of solvent, temperature, substrate, and catalyst on the relative amount of products due to both carbonylative coupling and direct coupling were studied.
