Gamma irradiation of benzonitrile shows that most of the identified products are related structurally to the parent molecule. The gaseous products are hydrogen, acetylene, and hydrogen cyanide. Nitrogen and cyanogen were not detected as products. Other than the gaseous products, benzene was the only product detected with a molecular weight less than benzonitrile. The three isomeric dicyanobenzenes were identified, and the relative reactivity for radiation-induced cyanation of benzonitrile is approximately 1 : 1 : 1.7 for the ortho : meta : para positions. The three isomeric cyanobiphenyls were identified, and the relative reactivity for radiation-induced phenylation of benzonitrile is approximately 1.4 : 1 : 1.9 for the ortho : meta : para positions; for phenylation with chemically generated phenyl radicals, the relative reactivity is 6 : 1 : 6. The six isomeric dicyanobiphenyls (one cyano group/phenyl ring) were identified, and the yields show that the radiation-induced cyanophenylation process is not random. Unidentified products with each group of isomeric cyano aromatic products represent a relatively small percentage of the yields of each group of isomeric products.
