| Outline of Final Research Achievements |
Phenols are valuable organic intermediates in the chemical industry. Most of these phenols are industrially produced by multistep processes. For example, a three step cumene process has been employed widely as a commercial process for the production of phenol. On the other hand, the direct catalytic hydroxylation of benzene to phenol with environment-friendly oxidants has attracted much attention.
Catalytic activity of iron complexes-encapsulated zeolite catalyst ([Fe(bpy)3]2+@Y) for oxidation of benzene increased with increasing the amount of water added into acetonitrile. Maximum value of catalytic activity was obtained, when the volume ratio of the solvents was equal (CH3CN : H2O = 1:1). After reaction at 24 h, the turnover number of [Fe(bpy)3]2+@Y was higher than that of [Fe(bpy)3](ClO4)2 as a homogeneous catalyst.
