A convenient metal-free decarbonylative radical conjugate addition of aliphatic aldehydes to electron-deficient alkenes is developed. With DTBP as an oxidant and radical-initiator, this reaction smoothly converts α-unsubstituted, α-mono-substituted and α-di-substituted aliphatic aldehydes into the corresponding primary, secondary and tertiary alkyl radicals, and subsequently allows for the cascade
开发了一种方便的无金属的脂肪族醛到无电子烯烃的脱羰基自由基共轭加成反应。用DTBP作为氧化剂和自由基引发剂,该反应可将α-未取代的,α-单取代的和α-二取代的脂肪醛平稳地转化为相应的伯,仲和叔烷基,随后可进行级联反应通过自由基共轭加成的C(sp 3)C(sp 3)键。
