Herein we report a photocatalytic oxidative radical addition reaction for the synthesis of unsymmetrical 1,4-dicarbonyl compounds. This reaction utilizes a desulfurization process to generate electrophilic radicals, which add to α-halogenated alkenes and undergo further oxidation to deliver 1,4-dicarbonyl compounds. This mild and highly efficient method provides a valuable alternative to known strategies
在此,我们报道了一种用于合成不对称 1,4-二羰基化合物的光催化氧化自由基加成反应。该反应利用脱硫过程产生亲电自由基,该自由基与 α-卤代烯烃相加并进一步氧化以产生 1,4-二羰基化合物。这种温和且高效的方法为已知策略提供了一种有价值的替代方法。
