THE C14 ISOTOPE EFFECT IN THE CONDENSATION OF BENZOYLBENZOIC ACID-CARBOXYL-C14 TO ANTHRAQUINONE-9-C14
Benzoylbenzoic acid-carboxyl-C 14 has been synthesized. The C 14 isotope effect in the condensation of this acid to anthraquinone-9-C 14 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 supp...

has been synthesized. The C
14
isotope effect in the condensation of this acid to anthraquinone-9-C
14
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. |
