I had a reaction in which I have to find the product .

I figured out something .

enter image description here

But my sir told me that this is a wrong product . I could understand why , as the reagent used act as decarboxylation .

  • $\begingroup$ There's no stabilized anion. Decarboxylation seems unlikely. $\endgroup$ – Zhe Mar 12 '17 at 16:44

Decarboxylation proceeds through free radical mechanism...and we see scope for rearrangement of radical...to obtain more substituted product(thermodynamic product....as we are supplying heat)and hence we can obtain the product 2-Methylbutan-2-ene...Hopefully thats your product

    $\begingroup$ Do you have a reference that the reaction proceeds through free radical mechanism? $\endgroup$ – Sawarnik Mar 12 '17 at 12:39

    $\begingroup$ I don't see why this reaction would proceed through a free radical mechanism. The reaction could just decarboxylate and pick up a proton on the far left carbon through resonance. $\endgroup$ – SendersReagent Mar 12 '17 at 12:59
  • $\begingroup$ sir,im still a student, and have learnt that thermal decarboxylation proceeds through a radical mech....in case you think otherwise...please do enlighten me too..regards@SendersReagent $\endgroup$ – Supernova Mar 12 '17 at 16:03
  • $\begingroup$ moreover...whatever charged intermediate it forms...it can rearrange to give a thermodynamic product $\endgroup$ – Supernova Mar 12 '17 at 16:04
