# What is wrong with the rection [closed]

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

I figured out something .

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

• There's no stabilized anion. Decarboxylation seems unlikely. – 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

• Do you have a reference that the reaction proceeds through free radical mechanism? – Sawarnik Mar 12 '17 at 12:39
• 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. – SendersReagent Mar 12 '17 at 12:59
• 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 – Supernova Mar 12 '17 at 16:03
• moreover...whatever charged intermediate it forms...it can rearrange to give a thermodynamic product – Supernova Mar 12 '17 at 16:04
