Copper(II)-catalyzed aerobic oxidation of primary alcohols to aldehydes in ionic liquid [bmpy]PF6

[GRAPHICS] A room-temperature aerobic oxidation of primary alcohols to aldehydes catalyzed by the three-component system acetamido-TEMPO/Cu(ClO4)(2)/DMAP in the ionic liquid [bmpy]PF6 has been developed, and the catalysts can be recycled and reused for five runs without any significant loss of catalytic activity.
