WebDevelopment of electrophilic fluorination reagents has always focused on removing electron density from the atom attached to fluorine; however, compounds containing nitrogen-fluorine bonds have proven to be the most economical, stable, and safe electrophilic fluorinating agents. WebElectrophilic aromatic substitution is an organic reaction in which an atom that is attached to an aromatic system (usually hydrogen) is replaced by an electrophile. Some of the most important electrophilic aromatic substitutions are aromatic nitration, aromatic halogenation, aromatic sulfonation, and alkylation and acylation Friedel–Crafts ...

"WebReagents commonly used in this type of reaction are carboxylic acid halides or acyl chlorides. Additionally, Lewis acid catalysts are used. There is a formation of the electrophile (generally acylium ion) by using a single pair from the chlorine of the H 3 C(C=O)Cl which is also used in filling the open octet of the aluminum belonging to AlCl 3 .

Any deactivating group directs the electrophile to the meta position. An activated ring means it undergoes an electrophilic aromatic substitution faster than benzene and deactivated rings react slower than benzene.
