What reaction is used for converting a primary amide into a primary amine containing one carbon atom less than the parent amide ?

Text Solution

Verified by Experts

By Hoffmann-bromamide reaction, i.e, by heating an amide with `Br_(2)` and KOH.
`underset("Amide")(RCONH_(2))+Br_(2) overset(Delta)toRNH_(2)+K_(2)CO_(3) + 2KBr + 2H_(2)O`

Hofmann rearrangement In the Hofmann rearrangement an unsubstitued amide is treated with sodium hydroxide and bromine to give a primary amine that has one carbon lesser than starting amide. Gneral reaction: If the migrating group is chiral then its configuration is retained. Electron releasing effects in the migrating group increase reactivity of Hofmann rearangement. Arrange the following amides according to their relative reactivity when reacted with Br_(2) in excess of strong base:
