An electrophile (or electrophilic @R05190@) is a @R05190@ that forms a bond to its reaction partner (the @N04249@) by accepting both bonding electrons from that reaction partner. An 'electrophilic @S06078@' is a @H02809@ reaction in which the @R05190@ supplying the @E02130@ acts as an electrophile. For example:
Electrophilic reagents are @L03508@. 'Electrophilic @C00874@' is @C00874@ by Lewis acids. The term 'electrophilic' is also used to designate the apparent polar character of certain @R05066@ as inferred from their higher relative reactivities with reaction sites of higher @E01986@.
