SpletLey-Griffith Oxidation. The Ley-Griffith reaction is the oxidation of primary or secondary alcohols to aldehydes or ketones. The central catalyst is tetra propylammonium … Tetrapropylammonium perruthenate (TPAP or TPAPR) is the chemical compound described by the formula N(C3H7)4RuO4. Sometimes known as the Ley–Griffith reagent, this ruthenium compound is used as a reagent in organic synthesis. This salt consists of the tetrapropylammonium cation and the perruthenate anion, RuO−4.
