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.
