Activated alkenes and dienes are converted into the corresponding alkenone in excellent yields (> 90%). In aqueous acetonitrile. the transformations are catalyzed by 2,2,6,6-tetramethyl-1-oxopiperidinium (TEMPO+) in the presence of water and 2,6-lutidine. TEMPO+ cations were regenerated electrochemically from the radical parent (TEMPO-) at a vitreous carbon anode. (c) 2005 Elsevier Ltd. All rights reserved.
