New organic chemistry youtube video: Making isobutyl bromide


https://www.youtube.com/watch?v=IE2yLWxwdT0

I made isobutyl bromide from isobutyl alcohol, red phosphorus, and elemental bromine

Nice work! If you want some sulfurol for free to halogenate, let me know. You can convert it to “bromethiazole” with that method.



We are the same perception looking out, from the same elements around the universe.

We are everything to be anything to begin with.

Im up for that. Its a primary alcohol with no possible rearrangement so it could be brominated with HBr

No problem, I messaged you.

Also I tried the sulfurol and HBr reaction in the past, but what I got unfortunately has unreacted sulfurol in it. I have a lot more sulfurol to play around with though. I am trying to modify the method and will try a reactor under pressure next for an experiment. (Using Hydrothermal Autoclave Reactor with PTFE Chamber)

Happy Holidays!

In that case, the phosphorus tribromide method is better because using an excess of phosphorus and bromine will completely brominate the alcohol. PBr3 is used when the alcohol and bromide are difficult to separate, so the reaction needs to go to completion
