Application

  • Perrhenic acid solution (HReO4) can be used in dehydrations of oximes, amides, and urea.
  • HReO4 can also catalyze azeotropic dehydration of syn- or anti-aldoximes to yield corresponding nitriles.
  • In combination with tertiary arsines, it gives a versatile catalytic system for epoxidation of alkenes with hydrogen peroxide.

It is also used to prepare highly conducting and superconducting synthetic metals.
