A new
chemical species AB, each
molecular entity of which is formed by direct combination of two separate molecular entities A and
B in such a way that there is change in
connectivity, but no loss, of atoms within the
moieties A and B. Stoichiometries other than 1:1 are also possible, e.g. a bis-adduct (2:1).
An
intramolecular adduct can be formed when A and B are groups contained within the same molecular entity.
This is a general term which, whenever appropriate, should be used in preference to
the less explicit term
complex. It is also used specifically for products of an
addition reaction. For examples, see
Lewis adduct,
Meisenheimer adduct,
π-adduct.
