Mechanistic experiments showed that the products were generated by selective cross-coupling of aliphatic radicals with fluoroalkenyl radicals. Silyl radical-mediated halogen abstraction enabled the protocol to be used for the monofluoroalkenylation of a broad range of alkyl and heteroaryl halides. The protocol could be carried out on a gram scale and was applied to cholesterol, indicating its utility
在这里,我们描述了一种方便的通用协议,用于涉及协同可见光光氧化还原催化和卤素提取的烷基
溴的单
氟烯基化反应。机理实验表明,产物是通过脂肪族自由基与
氟烯基自由基的选择性交叉偶联产生的。甲
硅烷基介导的卤素提取使该协议能够用于广泛的烷基和杂芳基卤化物的单
氟烯基化。该协议可以在克规模上进行,并应用于
胆固醇,表明其在后期单
氟烯基化反应中的效用。
