The main products of the reaction of cyanogen bromide with sodium benzoate at 250 ° to 300 °C. are carbon dioxide, benzonitrile, and sodium bromide. Tracer studies have shown that the carbon of the carbon dioxide is derived almost entirely from the cyanogen bromide.

Pyrolytic Decomposition

Cyanogen bromide reacts with the sodium salts of lower aliphatic acids at 250-300 °C to form an α-keto isocyanate as the primary product. The latter undergoes subsequent pyrolytic decomposition to a nitrile and carbon dioxide. A mechanism is proposed to account for the observed interchange of labelled carbon atoms between the CN group of the cyanogen bromide and the carboxyl group of the salt in the over-all reaction.

Sodium Phenylacetate

Benzylmalonyl Chloride reacts in the presence of sodium acetate in boiling benzene to give tribenzyl-phloroglucinol-triacetate, however with sodium chloroacetate to 3,5-dibenzyl-6-phenethylpyran-2,4-dion. In both cases trimerisation of benzylketene or benzylketene carboxylic acid chloride occurs. On the other hand, benzylmalonylchloride reacts with sodium benzoate and sodium phenylacetate via a dimeric benzylketene carboxylic acid chloride under the loss of phosgene to yield cyclopentadienyl derivatives.

Bromal labelled with C14 in the carbonyl group has been used to show that small amounts of carbon dioxide and carboxylic acids are produced in the radiolysis of aqueous bromal solutions. G values for the production of CO2 and carboxylic acid are about 7.5% and 15% of those for HBr production, respectively. The observed yield of carboxylic acid is in agreement with that found by titration.
