Organic functional groups, reaction with aniline

Reaction of Aniline with Organic Functional Groups. In the absence of catalysis by enzymes or metals, aniline undergoes nucleophilic addition reactions to quinone and other carbonyl groups in humic substances to form both heterocyclic and nonheterocyclic condensation products (9). In aqueous solution, aniline undergoes 1,4-addition (Michael addition) to both 1,2- and 1,4-quinones (10-14). The reaction of aniline with 1,4-benzoquinone, from the oxidation of hydroquinone, and with 4-methyl-1,2-quinone, from the oxidation of 4-methylcatechol, are illustrated here.
