malononitrile and cyanoacetic ester derivatives at the α-position based on transition-metal-catalyzed reaction (Cu, Fe, Mn, Co) with tert-butyl hydroperoxide giving unsymmetrical peroxides in 63-94% yields. The method is facile, does not require large excesses of reagents, and is amenable to gram-scale synthesis. peroxides - tert-butyl hydroperoxide - catalysis - oxidation - transition metals - malononitrile
基于过渡金属催化的叔丁基过氧化氢反应生成不对称的过氧化物,开发了一种新的方法,用于在α-位选择性地氧化α-单取代的丙二腈和氰基乙酸酯衍生物(Cu,Fe,Mn,Co)。 -94%的产率。该方法是容易的,不需要大量过量的试剂,并且适合于克级合成。 过氧化物-叔丁基过氧化氢-催化-氧化-过渡金属-丙二腈-氰基乙酸酯
