摘要：

The oxygenation of cyclohexene to cyclohexene oxide and cyclohexen-3-ol by (O)Fe IV TMP + (X) ( 1 ) at various temperatures was compared with the iodosylbenzene mediated reaction catalyzed by chloro-5,10,15,20-tetramesitylporphyrinatoiron(III) [Fe III (TMP)Cl]. The product ratios were found to depend on the axial ligand X in 1 and on the temperature in an unusual way. The results demonstrate that at least one reaction intermediate must be produced and further, that while the epoxidation proceeds via the formation of a complex between 1 and the olefin, the hydroxylation reaction proceeds by a non-intersecting reaction pathway not involving this complex.
