Thought of posting a little quickie here since I have the rights...

Predict the products and explain the mechanism for the following reaction(s) -:

Note : Oldies to whom I have explained this reaction are not allowed to answer :P
Hint : Think of acid catalysed enolisation as the first step.

pritish can u expain the mechanism of hydroslysis of an oxime

has it to do something with beckmann rearrangement

P.S i suck in chemistry , so may be the post is irrelevant

Sudharshan bhai...ankur asked me this question also. Hydrolysis of an oxime and Beckmann rearrangement are completely different. Hydrolysis can be done by different inorganic acids. Beckmann rearrangement is specifically done using sulfuric acid as a catalyst. Therein lies the difference. It's a good query though :)
