The oxidations of DL-atrolactic and 2-hydroxyisobutyric acids by cerium(IV) in sulphuric acid solutions

Abstract

Oxidations of DL-atrolactic and 2-hydroxyisobutyric acids by cerium(IV) in sulphuric acid solution occur in accordance with the empirical rate law: (see equation in article) where k₁ is a complex rate constant and A is an unspecified constant. Spectrophotometric results suggest complex formation between cerium(1v) and the organic acid, but no kinetic evidence was obtained. Manganese(11) catalyses the reactions. DL-Atrolactic acid is more reactive than 2-hydroxyisobutyric acid. The products of oxidations were acetophenone and acetone respectively.
