Epoxidation catalyzed by iron(III) and manganese(III) pyridine-2-carboxamido complexes

A series of Fe(III) and Mn(III) complexes containing N4 non-porphyrin pyridine-2-carboxamido ligands have been synthesized. Their catalytic abilities in epoxidation and the effects of reaction conditions such as temperature, solvent have been studied, leading to the highest yield of 92% for 4-methoxystyrene by using [Mn(bbpc)Cl(DMF)] (H2bbpc = 1,2-bis(4′-tert-butylpyridine-2′-carboxamido)-4,5-dichlorobenzene) as catalyst.
