Mahurin Honors College Capstone Experience/Thesis Projects
With iodobenzene diacetate [PhI(OAc)2] as the oxygen source, manganese(III) porphyrin complexes exhibit remarkable catalytic activity towards the selective oxidation of hydrocarbons. The readily soluble PhI(OAc)2 in the presence of small amount of water is more efficient oxygen source than the commonly used PhIO under the same conditions, leading to a potent catalytic system for the efficient oxidation of alkenes and activated hydrocarbons. When the reactions were carried out in the presence of a small amount of water at 50 oC, high selectivity for epoxides and excellent catalytic efficiency with up to 10,000 TON have been achieved in alkene epoxidations.
