参考标题:Rapid Formation Of Fluoren-9-Ones Via Palladium-Catalyzed External Carbon Monoxide-Free Carbonylation 作者:Hideyuki Konishi,Suguru Futamata,Xi Wang,Kei Manabe |发布日期:2018.5.2 摘要:Carbonylation Reaction For The Synthesis Of Fluoren‐9‐ones From 2‐halogenated Biphenyls Using Phenyl Formate As A Carbon Monoxide Surrogate Was Achieved. The Combined Use Of Cesium Carbonate And O‐anisic Acid Resulted In A Remarkable Rate Enhancement, Where The Reaction Was Complete Within 3 Min In Some Cases. Mechanistic Studies Indicated That The Turnover‐limiting Step Of The Reaction Was The C−h Bond‐cleaving
