· The Ley–Griffith reaction is utilized extensively in the selective oxidation of alcohols to aldehydes or ketones. The central catalyst is commercially available tetra-n-propylammonium perruthenate (TPAP, n-Pr 4 N[RuO 4]) which is used in combination with the co-oxidant N-methylmorpholine N-oxide (NMO).-oxide (NMO).

· The Ley–Griffith oxidation, utilising the tetra-n-propylammonium perruthenate (TPAP) reagent, is a very popular named reaction for performing this task. A variation on this reaction using a tetraphenylborate salt of N -methylmorpholine- N -oxide (NMO ⋅ TPB) is reported, which modulates the reactivity of TPAP such that anhydrous

COMBINATORIAL SOLID-PHASE SYNTHESIS Barry A. Bunin, in The Combinatorial Index, 1998For NMO/TPAP Oxidation. To a support-bound alcohol (0.30 mmol) was added a solution of N-methylmorpholine N-oxide (NMO) (352 mg, 3.00 mmol) in 10 mL of dry DMF, and then catalytic tetrapropylammonium perruthenate (TPAP) (21.1 mg, 0.06 mmol)

We present a simple, mild, and highly effective method for the direct conversion of primary alcohols to carboxylic acids. TPAP serves as the catalyst, and NMO·H2O plays a dual role, acting as the co-oxidant and as a reagent for aldehyde hydrate stabilization. This previously unknown stabilizing effect of geminal diols by N-oxides is the key for the efficiency of the

Abstract: A wide variety of novel non-hygroscopic N-oxide tetraphenylborate salts were synthesized and evaluated as co-oxidants in the Ley–Griffith (TPAP) oxidation of benzylic and allylic alcohols under non-anhydrous conditions. The novel DABCOO·TPB (2:1) salt was herein unearthed as a viable competitor to the first generation NMO·TPB (2:1
