Anions generated from primary arylamines react with substituted
nitrobenzenes to form σH-adducts, which, under
basic reaction conditions, undergo transformation to N-aryl-2-nitrosoamines. Competitive
substitution of reactive halogens in the nitroarenes,
which is observed in certain cases, can be controlled by the solvent
selected.
