A silver oxidant/Lewis acid catalyst cooperatively promoted three-component carbo-heterofunctionalization of alkenes is reported. A broad range of nucleophiles, including H2O, alcohols, and anilines, can combine with a variety of 1,3-dicarbonyl compounds or analogues as radical precursors to realize difunctionalization of various styrene derivatives. Interestingly, mechanistic investigations demonstrate
报道了一种银氧化剂/路易斯酸催化剂协同促进烯烃的三组分碳杂官能化。包括H 2 O、醇类和苯胺在内的多种亲核试剂可以与多种1,3-二羰基化合物或类似物作为自由基前体结合,实现各种苯乙烯衍生物的双官能化。有趣的是,机理研究表明,二齿膦配体的 Ag(I) 配合物可以快速氧化烯烃双键上添加初始自由基产生的自由基中间体,形成碳正离子中间体,这可能是其高产率和高选择性的原因。这样的反应。
