摘要/Abstract

以二叔丁基过氧化物（DTBP）作氧化剂，氯仿或四氯化碳作三氯甲基自由基源及反应溶剂，由芳酮衍生的烯醇硅醚经自由基加成串联消除反应合成了β，β-二氯-α，β-不饱和酮，反应无需金属催化剂，条件温和，烯醇硅醚底物具有良好的普适性.
关键词: 三氯甲基自由基, 烯醇硅醚, β,β-二氯-α,β-不饱和酮
Using di-tert-butyl peroxide (DTBP) as oxidant, chloroform or carbon tetrachloride as trichloromethyl radical source and reaction solvent, enol silyl ethers derived from aryl ketone was transferred to β,β-dichloro-α,β-unsaturated ketone by trichloromethyl radical addition/elimination. The conditions are mild with avoiding the use of metal catalysts, and the enol silyl ethers substrate has good universality.
Key words: trichloromethyl radical, enol silyl ethers, β,β-dichloro-α,β-unsaturated
