available starting materials: acid chlorides and sodium sulfinates. The facile generation of acyl radical species under the visible light photoredox conditions allows the formation of thiyl radical species from sodium sulfinates via multiple single electron transfer reactions, where the final acyl radical-thiyl radical coupling has been accomplished. The direct radical–radical coupling strategy offers a mild
已经开发了一种方便的可见光光氧化还原催化剂,用于从两种容易获得的起始原料:酰氯和亚磺酸钠合成硫酯。在可见光光氧化还原条件下容易地产生酰基基团物种使得可以通过多个单电子转移反应由亚磺酸钠形成硫基基团物种,其中已经完成了最终的酰基基团-噻吩基基团偶联。自由基-自由基直接偶联策略为重要的合成构件(例如硫酯)提供了温和且受控的光化学方法。
