Highly Selective Production of 2-Adamantanone by Photocatalytic Oxidation of Adamantane
2-Adamantanone was selectively produced by photocatalytic oxidation of adamantane in acetic acid using TiO 2 powders. The reactions were carried out at ambient and acetic acid reflux temperatures with and without an oxidant. Adding oxidant in refluxing acetic acid under irradiation remarkably increased conversion and selectivity. Rutile TiO 2 powders showed better conversion and selectivity in the presence of H 2 O 2 . The total conversion was 67% and the highest selectivity of 2-adamantanone was 89%.
