Preferred Label : Meisenheimer adduct;
IUPAC definition : A cyclohexadienyl derivative formed as Lewis adduct from a nucleophile (Lewis base)
and an aromatic or heteroaromatic compound, also called Jackson–Meisenheimer adducts.
In earlier usage the term 'Meisenheimer complex' was restricted to the typical Meisenheimer
alkoxide adducts of nitro-substituted aromatic ethers, e.g. Analogous cationic adducts,
such as: considered to be reaction intermediates in electrophilic aromatic substitution
reactions, are called 'Wheland intermediates', and sometimes, inappropriately, σ-complexes.;
