Abstract
Poly(vinylbenzyl)acetylacetonato complex of cobalt is an effective and stable catalyst for the epoxidation of cycloalkenes with molecular ox ygen under 25 degrees C with i-butyraldehyde as the sacrificial reduct ant. The acetylacetone ligand/Co mole ratio, the reaction time, and th e strain and electronic nature of cycloalkenes all affect the conversi ons of alkenes and selectivities to the corresponding epoxides. The ca talyst can be recycled at least seven times without loss of its activi ty.
