A polystyrene-based chelate resin, functionalized by tridentate iminodiacetate (ida) moieties, can easily immobilize various components by ion exchange or co-ordination.A multi-functionalized chelate resin imobilized with both ultrafine platinum particles and Fe(II) ions has been prepared successfully by co-ordinating Fe(II) ions to ida moieties after supporing ultrafine platinum particles.Electron transfer from the Fe(II) ions to oxygen produced Fe(III) ions and activated oxygen in the system, while the Fe(III) ions were reduced again to Fe(II) ions by molecular hydrogen via the platinum particles.The activation of oxygen molecules and/or a C-H bond of benzene are essential to the direct oxidation of benzene, Thus, benzene has been oxidized directly by activated oxygen to produce p-benzoquinone as the main product, indicating that the multi-functionalized chelate resin works like a dioxygenase enzyme.The oxidizing species for benzene was concluded to be the Fe(II)-dioxo complex, the co-ordinating oxygen of which is activated.
