General description

Tetrapropylammonium perruthenate is a mild oxidizing agent used for the oxidation of alcohols to corresponding carbonyl compounds. It is a non-volatile, air-stable, and readily soluble reagent, which can be used either stoichiometrically or catalytically with a suitable co-oxidant.

Application

Tetrapropylammonium perruthenate (TPAP) can be used as a catalyst:     
  • For the conversion of sulfides to sulfones by oxidation reaction.       
  • In the isomerization of allylic alcohols into the corresponding saturated carbonyl derivatives.      
  •  Along with N-methylmorpholine N-oxide (NMO) for the cleavage of glycol to carboxylic acids.

TPAP can also be used as an oxidizing reagent:
  • For the oxidation of benzyl alcohol to benzaldehyde and steroidal alcohols to corresponding ketones.
  • To convert N,N′-dihydroxyimidazolidines to nitronyl nitroxide free radicals.
  • To oxidize hydroxyl-substituted tri-n-butylammonium trifluoroborates to aldehydes and ketones without concomitant cleavage of the carbon-boron bond.
