Alcohol consumption : The PhI(OAc) 2 ‐derived hypervalent iodine reagent 1 acts as an oxidant in the conversion of primary and secondary alcohols 2 into carbonyl compounds 3 with good to excellent yields (see scheme). The bromide ion remaining from the preparation of [emim] + [BF 4 ] − (emim=1‐ethyl‐3‐methylimidazolium tetrafluoroborate) acts as a catalyst in the reaction. Primary alcohols are oxidized without any detectable overoxidation.
