Hi, i have a doubt choosing between this reaction and an ether formation, i have an alilic carbocation in a 1-buten and it reacts with KOH and EtOH, can it go through an SN1 as well as an E1? or do i need the specific EtOK and EtOH to make it go through an SN1?
I’d probably need to see the exact substrate, but if it’s using a strong base (KOH) it’s likely E2, not E1.
Hi James,
I need to write the mechanism for the conversion of iodocyclohexane to dibromocyclohexane.
I think I need to first write an E1 reaction to convert from iodocylcohexane to cyclohexene. Then, use Br2 in chloroform to convert from cyclohexene to dibromocyclohexane.
Is that correct?

It’s generally easier to get an E2 to occur, by using a strong base. But your general plan is correct.
