The product formed by the attachment
of an electrophilic
or nucleophilicentering group
or of a radical
to a ring carbon of an aromatic species so that a new σ-bond is formed and the original
is disrupted. (This has generally been called a 'σ-complex
', but adduct
is more appropriate than complex according to the definitions given.) The term may
also be used for analogous adducts to unsaturated (and conjugated) systems in general.
