摘要：
A simple, efficient, and eco-friendly procedure for the epoxidation of alkenes to epoxides with H2O2 catalyzed by Co(OAc)(2) in ionic liquid [C(12)py][PF6] has been developed. The reactions were carried out with alkene, Co(OAc)(2) (0.1 mmol), [C(12)py][PF6] (10 mL), and H2O2 (30 %, 11 mmol) at room temperature for 2-6 h. This atom-economical protocol affords the target products in good to high yields (88-98 %). The products can be separated by a simple extraction with organic solvent, and the catalytic system can be recycled and reused without loss of catalytic activity. A simple, efficient, and eco-friendly procedure for the epoxidation of alkenes to epoxides with H2O2 catalyzed by Co(OAc)(2) in ionic liquid [C(12)py][PF6] has been developed. [GRAPHICS]
