Friedel Crafts Acylation Deactivated Ring. B(c 6 f 5) 3. The inductive effect is a result of different electronegativities of the carbon in the ring and the atom connected to it.
PPT Chapter 17 Aromatic Substitution Reactions PowerPoint from www.slideserve.com
Substituents such as hydroxyl, alkoxyl & halogens are reduced first, the resulting unsubstituted aldehyde or ketone is then reduced to. The activation and deactivation of the aromatic ring are caused by inductive or resonance effects (or both). The second example illustrates the lability of functional substituents alpha to the carbonyl group.
The Activation And Deactivation Of The Aromatic Ring Are Caused By Inductive Or Resonance Effects (Or Both).
Alkylation also suffers from other limitations. Substituents such as hydroxyl, alkoxyl & halogens are reduced first, the resulting unsubstituted aldehyde or ketone is then reduced to. An activated ring means it undergoes an electrophilic aromatic substitution faster than benzene and deactivated rings react slower than benzene.
The Bottom Line Is That If We Add A Basic.
The second example illustrates the lability of functional substituents alpha to the carbonyl group. The inductive effect is a result of different electronegativities of the carbon in the ring and the atom connected to it. The major limitation common between the alkylation and acylation is their sensitivity towards the nature of the aromatic compound.
