Abstract: Palladium-catalyzed three-component coupling reactions of benzyl chlorides, allyltributylstannane, and carbon monoxide were investigated. These three-component coupling reactions proceeded smoothly in the presence of Pd(PPh3)4 to give benzyl allyl ketone products, which could transform to α,β-unsaturated ketone compounds 6a–6n after purification via basic alumina column chromatography. α,β-Unsaturated ketone compounds 6b, 6d–h, 6j, 5l, and 6l–6n are unknown compounds, and their structure was characterized by infrared spectroscopy, 1H nuclear magnetic resonance spectroscopy, 13C nuclear magnetic resonance spectroscopy, and high-resolution mass spectroscopy.

Key words: benzyl chloride, carbon monoxide, allyltributylstannane, coupling, α,β-unsaturated ketone
