What happens during the displacement of aromatic compounds?
- During the displacement, the p orbital that partially bonds to the nucleophile and leaving group also overlaps with the ? electrons of the aromatic ring. This conjugationlowers the energy of the TS, and so enhances reaction rate. Ch17 Reactions of Aromatic Compounds (landscape).docx Page57 S N
How does a sigma complex regain its aromaticity?
- The sigma complex wishes to regain its aromaticity, and it may do so by either a reversal of the first step (i.e. regenerate the starting material) or by loss of the proton on the sp3carbon (leading to a substitutionproduct). When a reaction proceeds this way, it is electrophilic aromatic substitution.
Why is benzene aromatic but not aromatic?
- Reactions of Aromatic Compounds Just like an alkene, benzene has clouds of ? electrons above and below its sigma bond framework. Although the ? electrons are in a stable aromatic system, they are still available for reaction with strong electrophiles. This generates a carbocation which is resonance stabilized (but not aromatic).
Are electrons in a stable aromatic system?
- Although the ? electrons are in a stable aromatic system, they are still available for reaction with strong electrophiles. This generates a carbocation which is resonance stabilized (but not aromatic).
