Preferred Label : σ-adduct;
IUPAC definition : The product formed by the attachment of an electrophilic or nucleophilic entering
group or of a radical to a ring carbon of an aromatic species so that a new σ-bond
is formed and the original conjugation 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.;
