Schmidt Reaction - Reaction Mechanism
... Reaction with hydrazoic acid forms the protonated azido ketone 2, which goes through a rearrangement reaction with the alkyl group R, migrating over the C-N bond with expulsion ... The protonated isocyanate is attacked by water forming carbamate 4, which after deprotonation loses carbon dioxide to the amine ... rearrangement except that in this reaction the azide is protonated and hence with different intermediates ...
