At a glance:-: The Demjanove rearrangement is a chemical reaction where primary amines with nitrous acid to give rearranged alcohols. This reaction involves substitution by a hydroxy group with a possible ring expansion.
This reaction is named after the Russian Chemist Nikolai Jakovlevich Demjanove.
Ring expansion:- It occurs as a carbocation rearrangement when an unstable cycloalkane is near a carbocation. They key is to recognize when a ring is unstable, and this type of rearrangements that will help it become more stable.
Carbocation rearrangement:-
They are extremely common in Organic Chemistry reaction. They are defined as the movement of a carbocation from an unstable state to a more stable state through the use of various structural reorganizational shift within the molecule.
