A question related to Hofmann elimination
« on: March 05, 2014, 04:49:27 AM »
Please help me with this problem!
What is the mechanism of this reaction in the attached figure?
I think it is a reaction which starts with the Hofmann elimination, but I don't understand what happens after the elimination.

I don't think you can get there via a Hofmann pathway...

My guess is some sort of sigmatropic rearrangement followed by rearomatization; I've drawn a plausible mechanism from the methyl anion, but you could also get there from the benzylic anion.

Thank you for answering!
So I am wrong at the very beginning...
May I ask why it won't just go through the Hofmann elimination pathway and yield an alkene product?
