The conversion of the ipso-intermediates (1) and (2) into the corresponding o-nitroamines in aqueous sulphuric acid at 0 deg C has been followed by u.v. spectrometry.The reactions are first-order and the form of the rate profile shows that either the 1,3-
ipso-Attack in the Nitration of Aromatic Amines. Part 3. Evidence for Two Mechanisms of ipso-Attack
Al-Omran, Fatima,Ridd, John H.

Studies on the nitration of NN-dimethyl-4-methylaniline (1a) have been extended to NN-dimethyl-3,4-dimethylaniline (1b) and NN-dimethyl-3,4,5-trimethylaniline (1c).All three amines react with nitric acid in 60-70percent sulphuric acid at 0 deg C by the ni
