摘要
Two solutions, one consisting of bpy/TEMPO/NMI and the other bpy/ABNO/NMI (bpy =2,2'-bipyridyl; TEMPO = 2,2,6,6-tetramethylpiperidine N-oxyl, ABNO = 9-azabicyclo[3.3.1]nonane N-oxyl; NMI = N-methylimidazole), in acetonitrile are shown to have good long-term stability (>= 1 year) under air at 5 degrees C. The solutions may be combined in appropriate quantities with commercially available [Cu(MeCN)(4)]OTf to provide a convenient catalyst system for the aerobic oxidation of primary and secondary alcohols.
