Tetrahydrofuran (THF) was oxidized selectively with molecular oxygen catalyzed by magnesium oxide‐based polyalumazane‐supported platinum complexes under mild conditions. The selective oxidation of C–H bond α to the oxygen atom of ether and the oxidative path to ester other than ring cleavage to carboxylic acid were controlled by carrying out the reaction at 60°C with nitroethane as solvent. The platinum loading and the reaction time greatly affected the yield of γ‐butyrolactone whereas the selectivity always remained at 100%. 76.92% γ‐butyrolactone was obtained with 0.2811 mmol platinum loading per gram support within 12 hr. The single product of the THF oxidation was confirmed by 1 H‐nuclear magnetic resonance. X‐ray photoelectron spectroscopy data also confirmed the more recent report on the activation of the C–H bond by the null valent platinum from the viewpoint of supported platinum catalyst. The oxidation path was also suggested.
