Preferred Label : attachment;
IUPAC definition : A transformation by which one molecular entity (the substrate ) is converted into
another by the formation of one (and only one) two-centre bond between the substrate
and another molecular entity and which involves no other changes in connectivity in
the substrate. For example, the formation of an acyl cation by attachment of carbon
monoxide to a carbenium ion (R sup class plus /sup ): The product of an attachment
may also be the adduct of the two reactants, but not all adducts can be represented
as the products of an attachment. (For example, the Diels–Alder cycloaddition: results
in an adduct of buta-1,3-diene and ethene, but the reaction cannot be described as
an attachment since bonds are formed between more than two centres.);
