ORGANIC RADIATION CHEMISTRY.
Abstract
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 and/or 4,4'-bisdimethylaminodiphenylmethane, formed via the ion (PhNMe:CH2)+. 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.
