Abstract
Co-catalyzed epoxidation of cyclic alkenes proceeds in ionic liquid media (1-ethyl-3-methylimidazolium hexafluorophosphate). Epoxidation of the alkenes to respective epoxides was greatly accelerated by the use of a cobalt-based catalyst in the presence of H<inf>2</inf>O<inf>2</inf> as an oxidant. The catalyst in ionic liquid [Emim]PF<inf>6</inf> was recycled and reused for about seven times. © 2014 Académie des sciences. Published by Elsevier Masson SAS. All rights reserved.
