参考标题:Double Ligands Enabled Ruthenium Catalyzed Ortho ‐c−h Arylation Of Dialkyl Biarylphosphines: Straight And Economic Synthesis Of Highly Steric And Electron‐rich Aryl‐substituted Buchwald‐type Phosphines 作者:Liang‐neng Wang,Pan‐ting Tang,Ming Li,Jia‐wei Li,Yue‐jin Liu,Ming‐hua Zeng |发布日期:2021.6.8 摘要:A Double-Ligands Enabled Ruthenium Catalyzed C(Sp2)−h Arylation Of Dialkyl Phosphines Is Described, Which Provides A Straight Access To Aryl-Substituted Dialkyl Phosphine Ligands. The Combination Of 1,3-Diketone And Amino Acid Ligands Is Essential For This Transformation. An Important Six-Membered Cycloruthenium Intermediate Was Successfully Isolated And Characterized By X-Ray Diffraction. Mechanistic
