selective cleavage of acetal-derived alkylsilyl peroxides, followed by the formation of a carbon-carbon bond is reported. The reaction proceeds under mild reaction conditions and exhibits a broad substrate scope with respect to the acetal moiety and the carbon electrophile. Mechanistic studies suggest that the present reaction proceeds through a free-radical process involving carbon radicals generated
报道了一种基于自由基的新颖方法,用于铁催化的乙缩醛衍生的烷基甲硅烷基过氧化物的选择性裂解,然后形成碳-碳键。反应在温和的反应条件下进行,并且相对于缩醛部分和亲电碳表现出宽泛的底物范围。机理研究表明,本反应通过自由基过程进行,该自由基过程涉及由乙缩醛部分内碳-碳键的均相裂解产生的碳自由基。还描述了该方法在糖衍生的烷基甲硅烷基过氧化物中的合成应用。
