Electrochemical synthesis of nitroanilines

Alkylamines and amides are readily prepared by nucleophilic aromatic substitution of hydrogen in nitroarenes by electrochemical oxidation. Useful yields (15-85%) are achieved in a simple direct and regioselective amination process. The synthetic method has been examined in the absence and presence of external bases, used to promote the first step of the nucleophilic aromatic substitution reaction, i.e. the nucleophilic attack. In both cases, good results were obtained. The unreacted starting material can easily be recovered at the end of the electrochemical oxidation process. This new method represents an environmentally favourable route to amino- and amido-substituted nitroaromatic compounds.

Rate constants are reported for reaction of 4-substituted 1-chloro-2,6-dinitrobenzenes 1, 6-substituted 1-chloro-2,4-dinitrobenzenes 2, and some of the corresponding 1-phenoxy derivatives, 3 and 4, with n-butylamine, pyrrolidine and pi-peridine in acetoni
Rapid scan spectrophotometric and kinetic studies in the reactions of 4-substituted-2,6-dinitro-N-n-butylanilines with n-butylamine in dimethyl sulfoxide

The reactions of 2,4,6-trinitro-N-n-butylaniline 6a, 4-cyano-2,6-dinitro-N-n-butylaniline 6b and 4-methoxycarbonyl-2,6-dinitro-N-n-butylaniline 6c with n-butylamine in dimethyl sulfoxide have been investigated by rapid scan spectrophotometry and a stopped-flow method. 6a and 6b react competitively with n-butylamine to give the conjugate bases due to fast proton transfer and anionic σ-adducts by the addition of amine at the 3-position, while 6c reacts to give the conjugate base. The distinct spectra of only the conjugate bases have been observed. The effect of substituents on rate and equilibrium constants obtained for these competitive reactions is discussed.
