Adduct purification
Adduct purification is a technique for preparing extremely pure simple organometallic compounds, which are generally unstable and hard to handle, by purifying a stable adduct with a Lewis acid and then obtaining the desired product from the pure adduct by thermal decomposition.

Flavanol-anthocyanin adduct
Flavanol-anthocyanin adducts are formed during wine ageing through reactions between anthocyanins and tannins present in grape, with yeast metabolites such as acetaldehyde. Acetaldehyde-induced reactions yield ethyl-linked species such as malvidin glucoside-ethyl-catechin. This type of compound has ...

Spin trapping
of radicals is too short to detect with EPR, compounds known as spin traps are used to react covalently with the radical products and form more stable adduct The spin adduct usually yields a distinctive EPR spectrum characteristic of a particular free radical that is trapped.

Manganese-mediated coupling reactions
Copper(II) acetate is sometimes needed to facilitate the oxidation of adduct radicals to carbocations. Addition to an olefin then occurs, generating adduct radical 2.
