Gamma-radiolysis of pure NN-dimethylaniline yields NN-dimethyl-NN-diphenylethylenediamine through dimerisation of the N-methylanilinomethyl radical together with hydrogen, methane, and N-methylaniline but when the radiolysis is carried out in the presence of acid the first named product is replaced by N-p-dimethylaminobenzyl-N-methylaniline andor 4,4-bisdimethylaminodiphenylmethane, formed via the ion PhNMeCH2. The two latter products are also formed by photolysis of the amine in the presence of acid. Gamma-radiolysis of NN-dimethyl-p-toluidine gives NN-dimethyl-NN-di-p-tolylethylenediamine and 4,4-bisdimethylaminobibenzyl. Gamma-irradiation or photolysis of NN-dimethylaniline in the presence of N-phenylmaleimide yields 1,2,3,4-tetrahydro-1-methylquinoline-3,4-dicarboxylic-N-phenylimide, through a radical reaction. A similar reaction occurs with other NN-dialkylanilines, N-phenylpyrrolidine, or N-phenylpiperidine in the presence of olefinic compounds such as N-phenylmaleimide, diethyl maleate, cyclohexene, or cyclopentene.
