摘要：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 alpha,beta-unsaturated ketone compounds 6a-6n after purification via basic alumina column chromatography. alpha,beta-Unsaturated ketone compounds 6b, 6d-h, 6j, 5l, and 6l-6n are unknown compounds, and their structure was characterized by infrared spectroscopy, H-1 nuclear magnetic resonance spectroscopy, C-13 nuclear magnetic resonance spectroscopy, and high-resolution mass spectroscopy.
