A metal‐ and oxidant‐free catalytic method for accessing structurally diverse thioesters from readily accessible, widespread aldehydes, is described. A strategy of a simple organic 9,10‐phenanthrenequinone‐promoted hydrogen atom transfer (HAT) with visible light was successfully implemented to selectively generate acyl radicals without inducing crossover reactivity of thioester products. The preparative
描述了一种无金属和无氧化剂的催化方法,该方法可从易于获得的广泛醛中获得结构多样的硫酯。成功实施了一种具有可见光的简单有机9,10-菲醌促进的氢原子转移(HAT)策略,可选择性地产生酰基自由基,而不会引起硫酯产物的交叉反应性。广泛的底物范围和广泛的官能团耐受性证明了该方法的制备能力,并且使复杂结构的后期修饰成为可能,这是现有协议难以实现的。
