TEMPO-Derived Oxoammonium Salts as Versatile Oxidizing Agents

摘要

The diverse synthetic applications of 4-acetamido-2,2,6,6-tetramethylpiperidine-1-oxoammonium tetrafluoroborate (4) as a versatile, user-friendly reagent are surveyed. In addition to alcohol oxidation, its use in a variety of other functional-group transformations, such as C-H bond activation and oxidative esterification, are also highlighted.
