title: Alumina supported potassium permanganate: an efficient reagent for chemoselective dehydrogenation of 2-imidazolines under mild conditions.
abstract: Potassium permanganate supported on alumina was found to be an efficient reagent system for dehydrogenation of 2-imidazolines to imidazoles under mild conditions at room temperature. Selective oxidation of 2-alkylimidazolines in the presence of 2-arylimidazolines was achieved using this reagent system. 2-Imidazolines were also selectively converted to their corresponding imidazoles in the presence of other oxidizable functional groups such as sulfide, ether, aldehyde, acetal and THP ether. The oxidation procedure described here is easy to carry out and does not require strict reaction conditions.
