Abstract
The homolytic phenylation of 3- and 4-picoline under the conditions of the Gomberg–Hey reaction has been studied quantitatively. The methyl group in both picolines was found to activate the nucleus to the same extent. All the nuclear positions in both systems, except for C5 in 3-picoline, were slightly activated as compared with any one position in benzene. The significance of these results is discussed.
