- Alkane oxidation catalysed by a self-folded multi-iron complex
-
A preorganised ligand scaffold is capable of coordinating multiple Fe(II) centres to form an electrophilic CH oxidation catalyst. This catalyst oxidises unactivated hydrocarbons including simple, linear alkanes under mild conditions in good yields with selectivity for the oxidation of secondary CH bonds. Control complexes containing a single metal centre are incapable of oxidising unstrained linear hydrocarbons, indicating that participation of multiple centres aids the CH oxidation of challenging substrates.

- Oxy-Functionalization of Adamante-1-acetic Acid and Adamantane-1-carboxylic Acid by the Ferrous Iron-Molecular Oxygen System in Aqueous Solution
-
Oxygenation reactions of adamantanes with ferrous iron-molecular oxygen in phosphate buffer were investigated and the structures of the products were elucidated.In the reaction of adamantane-1-acetic acid (1a), five oxygenated products, the C(2)-oxo, C(4)-oxo, C(2),C(6)-dioxo, C(4)-ol, and C(3)-ol derivatives, were obtained.Similar oxygenation also occurred in the reaction of adamantane-1-carboxylic acid (2a) to give three products, the C(4)-oxo, C(4)-ol, and C(3)-ol derivatives.The oxy-functionalization of 1a and 2a in 0.5M phosphate buffer (pH 6.8) was found to occur almost quantitatively on addition of an appropriate amount of ferrous iron.
