Alkylsilyl peroxides were generated in situ from the corresponding alkyl hydroperoxides using organosilicon compounds of the type Me3SiX (X = CN, N3, and halogens) and an amine base. Subsequent in situ copper-catalyzed homolytic cleavage of the alkylsilyl peroxides afforded alkyl radicals, which were then trapped with X (X = CN, N3, and halogens) to furnish products with new carbon-carbon, carbon-nitrogen
使用Me 3 SiX(X = CN、N 3和卤素)类型的有机硅化合物和胺碱从相应的烷基氢过氧化物原位生成烷基甲硅烷基过氧化物。随后在铜催化下对烷基过氧化物进行原位均裂,得到烷基自由基,然后用 X(X = CN、N 3和卤素)捕获烷基自由基,从而为产品提供新的碳-碳、碳-氮或碳-卤素债券收益高。
