摘要:A Convenient Procedure For Converting Aryl Alcohols To Aryl Fluorides Via Aryl Nonafluorobutylsulfonates (Aronf) Is Presented. Moderate To Good One-Pot,Two-Step Yields Were Achieved By This Nonaflation And Microwave-Assisted,Palladium-Catalyzed Fluorination Sequence. The Reductive Elimination Step Was Investigated By Dft Calculations To Compare Fluorination With Chlorination,Proving A Larger Thermodynamic Driving Force For The Aryl Fluoride Product. Finally,A Key Aryl Fluoride Intermediate For The Synthesis Of A Potent Hcv Ns3 Protease Inhibitor Was Smoothly Prepared With The Novel Protocol.
