Abstract
Benzoylbenzoic acid-carboxyl-C14 has been synthesized. The C14 isotope effect in the condensation of this acid to anthraquinone-9-C14 in concentrated sulphuric acid has been measured and the ratio of the reaction rates, k(14)/k(12), found to be 1.074 ± 0.003. It is suggested that this result supports the mechanism for this reaction proposed by Newman.Keywords
