Which reagent can be used for the alkylation of aromatic nitro compounds
Options
(a) Methyl-sulfinyl carbanion
(b) Methyl-iodide
(c) Dimethyl-sulphate
(d) Methyl-lithium
Correct Answer:
Methyl-sulfinyl carbanion
Explanation:
Ar – NO₂ group is ring deactivating group. So it does not favour electrophilic alkylation in benzene ring . Therefore nitrobenzene undergoes nucleophilic alkylation through carbanion intermediate. So the reagent used is methyl sulfinyl carbaion.
