WebNov 1, 2024 · Here, aniline as well as substituted anilines (e.g., methyl, chloro, and bromo-aniline) was selected as representative compounds. Firstly, the kinetics of Mn (VII) reactions with anilines were determined in synthetic solutions over a wide pH range of 5–9. WebBecause of their high nucleophilic reactivity, aniline and phenol undergo substitution reactions with iodine, a halogen that is normally unreactive with benzene derivatives. The mixed halogen iodine chloride (ICl) provides a more electrophilic iodine moiety, and is effective in iodinating aromatic rings having less powerful activating substituents.
