actually , its a pinacole-pinacolone type reaction. u must be wondering how ?

wherever ders an -OH group adjacent by a positive charge , then pinacole-pinacolone type reaction cn take plce ( provided : der must be some migrating group attached to the carbon to which -OH group is attached. )

here HNO₂ group displaces NH₂^- group and a +ve charge appears. then pinacole-pinacolone reaction takes place.

thx

no.. wait.. it is special kind of reaction.. ring expansion takes place here for sure... but I'm not able to recollect that reaction at all..

oh.. ok. okk.. I think aieee did that only.. It's Demjanov reaction.
