Lanthanum Triflate–Catalyzed Rapid Oxidation of Secondary Alcohols Using Hydrogen Peroxide Urea Adduct (UHP) in Ionic Liquid

<div><p></p><p>A convenient and efficient protocol for the oxidation of secondary hydroxyl group to ketone using hydrogen peroxide–urea adduct and catalytic (CF₃SO₃)₃La in ionic liquid has been developed. A number of 1,2-diols, α-hydroxyketones, and other aromatic and aliphatic secondary alcohols have been successfully oxidized to the corresponding ketones using this protocol in good yields and short reaction times.</p> <p>[Supplementary materials are available for this article.
