Abstract
A novel 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) radical bearing an ionic liquid-type appendage has been prepared, and its catalytic activity for the selective oxidation of alcohols to the corresponding carbonyl compounds in ionic liquid-aqueous biphasic conditions has been investigated. The ionic liquid-supported TEMPO radical shows catalyst properties similar to those of non-supported counterpart in terms of activity and selectivity, and can be easily recycled and reused without loss of activity and selectivity.Keywords
