Description générale

Stahl Aerobic Oxidation TEMPO solution contains 1-methylimidazole (NMI), 2,2′-bipyridyl (bpy), and TEMPO. It is widely employed for the oxidation of alcohols.

Application

This convenience solution can be used in tandem with tetrakisacetonitrile copper(I) triflate (685038) for the oxidation of primary alcohols through aerobic conditions developed by the Stahl Research Group.

This protocol describes a practical laboratory-scale method for aerobic oxidation of primary alcohols to aldehydes, using a chemoselective Cu(I)/TEMPO (TEMPO = 2,2,6,6-tetramethyl-1-piperidinyloxyl) catalyst system. The catalyst is prepared in situ from commercially available reagents, and the reactions are performed in

Alcohol oxidation is one of the most frequently performed oxidation reactions in organic chemistry. The aldehyde and ketone products of alcohol oxidation are useful intermediates en route to complex molecules.

TEMPO (2,2,6,6-Tetramethylpiperidinyloxy or 2,2,6,6-Tetramethylpiperidine 1-oxyl) and its derivatives are stable nitroxy radicals used as catalysts in organic oxidation reactions. TEMPO was discovered by Lebedev and Kazarnovskii in 1960. The stable free radical nature of TEMPO is due to the presence of bulky substituent groups, which hinder the reaction of the free radical with other molecules.
