The identities of the supported metal complexes were confirmed by FT-IR, SEM-EDS and AAS. TGA indicated that the catalysts were thermally stable up to 230°C. These catalysts have been tested for the functionalization of n-hexane with molecular O2. The best result was obtained with CuFeL 2 over Al2O3 (ca. 19% overall conversion; 78% selectivity: hexan-2-one plus hexan-2-ol) and promoted conversion could be obtained with 2-pyrazinecarboxylic acid (as co-catalyst). The effects of various factors (temperature, O2 pressure, reaction time and catalyst concentration) were also investigated in detail. The impact of both C- and O- centred radical traps was also assessed to establish a radical mechanism.
