The catalyst system is compatible with a wide range of functional groups and shows a high selectivity for 1 alcohols.The oxidations of eight different alcohols, described here, include representative examples of each reaction condition and purification method. developed the catalyst system described here and performed the experimental work described here. Reaction times vary from 20 min to 24 h, depending on the alcohol, whereas the purification methods each take about 2 h.

/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 a common organic solvent (acetonitrile) with ambient air as the oxidant. confirmed the reproducibility of experimental procedures and performed the oxidation reaction and product characterization for Table 1 (entry 3). Three different reaction conditions and three procedures for the isolation and purification of the aldehyde product are presented.
