Tetrapropylammonium perruthenate

Tetrapropylammonium perruthenate is a Ru catalyst precursor and 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

As a catalyst it is used

1) For the conversion of sulfides to sulfones

2) In the isomerization of allylic alcohols into the corresponding saturated carbonyl derivatives

3) In combination with N-methylmorpholine N-oxide (NMO) for the cleavage of glycol to carboxylic acids

4) For the oxidation of benzyl alcohol to benzaldehyde and steroidal alcohols to corresponding ketones.

5) To convert N,N′-dihydroxyimidazolidines to nitronyl nitroxide free radicals

6) To oxidize hydroxyl-substituted tri-n-butylammonium trifluoroborates to aldehydes and ketones without concomitant cleavage of the carbon-boron bond.
