Dr. Zhi He and Prof. Dr. Timothy F. Jamison Continuous-Flow Synthesis of Functionalized Phenols by Aerobic Oxidation of Grignard Reagents Angewandte Chemie International Edition 53
Putting on airs: Aerobic oxidation of (hetero)aryl Grignard reagents using compressed air proceeds with a gas-liquid continuous-flow system, thus enabling preparation of fucntionalized phenols. By integrating an in-line generation of ArMgBr intermediates with the aerobic oxidation, ortho-functionalized phenols can be assembled. The method demonstrates good functional-group (FG) compatibility, mild reaction conditions, and short reaction times.
