    • Control experiments were carried out at 60 and 160°C without Pt species : the aerobic oxidation of 6a did not proceed at 60°C at all, whereas at 160°C under neat conditions 8a was obtained in 64% yield (24 h; not optimized); Y. Uozumi, Y. M. A. Yamada, unpublished results.

    • The obtained 2-octanone (Table 1, entry 23) was not contaminated with platinum residue (checked by inductively coupled plasma (ICP) analysis). Over 99.9% of Pt was retained in the resin: ICP analysis showed that leaching of Pt to the aqueous solution was less than 1 ppm, and the aqueous filtrate did not show any catalytic activity.

    • A referee has argued that the oxidation with leached homogeneous platinum species is still plausible as the metal species may redeposit back on the heterogeneous surface.
