Description

MilliporeSigma Sigma Organics products encompass a wide range of quality reagents, solvents, catalysts, and building blocks for organic synthesis. From benchtop discovery to process development and scale-up, Sigma Organics solutions are built to meet the needs of synthetic chemists.

  • Perfluoro-1-butanesulfonyl fluoride (nff) reacts with alcohols, including phenols, to yield nonafluorobutanesulfonate esters (nonaflates)
  • Nonaflates can be used as electrophiles in several palladium-catalyzed cross coupling reactions and in buchwald-hartwig amination.nff can also be used to prepare aryl nonaflates by reacting with corresponding aryloxysilanes in the presence of fluoride ion
