Abstract
The reaction of13N to form13N-labelled compounds was studied in acetic acid-d4 as a function of the halogenoacetic acid concentration and in malonic acid-d4 as a function of the intermolecular distance of target malonic acid-d4 at 195 and 295±6 K. In both deuterated carboxylic acids,13N atoms were found in several forms in the order of radiochemical yields,13NH3>H13NO3>[13N]aminoacid>HC13N. The yield of [13N]glycine formed in acetic acid-d4 were markedly enhanced by iodoacetic acid and slightly by chloroacetic acid. In malonic acid-d4, the yield of13NH3 was directly proportional to the cubic root of the molar ratio, {D2O/CD2 (COOD)2}, while the yields of H13N3, [13N]aminomalonic acid and HC13N were inversely proportional to the cubic root of the molar ratio. The mechanism of the formation of the13N-compounds are discussed.
