Aromatic Substitution Reactions
Aromatic Substitution Reactions:
The aromatic structure provides significant additional stability to the molecule. Substitution reactions allow the aromatic structure to remain, whereas additions would change the C-C bonding away from being aromatic.
A nucleophilic aromatic substitution is a substitution reaction in organic chemistry in which the nucleophile displaces a good leaving group, such as a halide, on anaromatic ring. There are 6 nucleophilic substitution mechanisms encountered witharomatic systems: the SNAr (addition-elimination) mechanism.
Another reaction of aromatic compounds is electrophilic aromatic substitution, where a C-H bond is broken and a new C-E bond (E being an electrophilic atom such as Cl, Br, N…) is formed. Alkenes Give “Addition” Products Upon Reaction WithElectrophiles.
