General description

Potassium osmate(VI) dihydrate is a hydroscopic transition metal compound soluble in water and methanol, widely used as a reagent/catalyst to synthesize Os compounds.

Application

Potassium osmate(VI) dihydrate can be used:
  • As a reagent for the stereoselective synthesis of 2,3,4-unprotected β-N-Glycopyranosides via palladium-catalyzed Tsuji-Trost amination.
  • As a catalyst for asymmetric synthesis of carboranylated diols bearing two adjacent stereocenters.
  • To prepare Osmium complexes for voltammetric analysis of polysaccharides.
