The silver‐catalyzed oxidative C(sp3)−H/P−H cross‐coupling of 1,3‐dicarbonyl compounds with H‐phosphonates, followed by a chemo‐ and regioselective C(sp3)−C(CO) bond‐cleavage step, provided heavily functionalized β‐ketophosphonates. This novel method based on a readily available reaction system exhibits wide scope, high functional‐group tolerance, and exclusive selectivity.
1,3-二羰基化合物与H-膦酸酯的银催化氧化C(sp 3)-H / PH交叉偶联,随后是化学和区域选择性C(sp 3)-C(CO)键-裂解步骤,提供功能强大的β-酮膦酸酯。这种基于现成反应系统的新颖方法具有广泛的应用范围,较高的官能团耐受性和选择性。
