Resonance electron-donating group

ChemActivity 19 EAS 353 Memorization Task 19.7 Identifying Resonance Electron-donating Groups... [Pg.353]

An atom with a lone pair next to an aromatic ring will function as a resonance electron-donating group... [Pg.353]

EAS reactions in which the ring has one or more strong electron-donating groups (= resonance electron-donating groups) often result in products with more than one electrophile on the ring. As we will see in the next section, this is especially true for Friedel-Crafts alkylations, (but not F-C acylations ) ... [Pg.353]

No ordinary EAS reactions work with very deactivated rings. As a mle of thumb, a ring is considered very deactivated if it has two resonance electron-withdrawing groups (and no resonance electron-donating groups to counterbalance this). [Pg.373]
