Surface-Modified Photochemistry. Preparation of Silica-Supported Fe3(CO)12 via Irradiation of Adsorbed Fe(CO)5

Article abstract of DOI:10.1021/ja00388a019

The photochemistry of silica-adsorbed Fe(CO)5 has been studied.IR and UV-visible spectra show that the only significant product is Fe3(CO)12 rather than Fe2(CO)9, which is the product observed following irradiation of Fe(CO)5 in the gas or liquid phase or in solution.Formation of Fe3(CO)12 is discussed in terms of a mechanism involving rapid secondary thermal reactions of a surface-complexed form of Fe(CO)4.
