General description

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
