摘　　要：研究了苄基氯衍生物、CO和三丁基烯丙基锡在零价钯催化剂(Pd(PPh3)4)存在下的反应,结果表明,可有效发生三组分偶联反应,生成不饱和酮化合物.再经碱性氧化铝柱提纯后,转化为α,β-不饱和酮化合物6a～6n,其中,6b,6d～6h,6j,5l和6l～6n等未见文献报道,其结构经红外光谱、1H和13C核磁共振以及高分辨质谱表征确定.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.
