A nucleophile (or nucleophilic
reagent) is a
reagent that forms a
bond to its reaction partner (the
electrophile)
by donating both bonding electrons. A '
nucleophilic substitution
reaction' is a
heterolytic reaction in which the
reagent supplying the
entering group acts as a nucleophile. For
example:
The term '
nucleophilic' is also used to designate the
apparent polar character of certain
radicals,
as inferred from their higher relative reactivity with reaction sites
of lower
electron density. Nucleophilic reagents are
Lewis bases.
