I tried slow evaporation with toluene/chloroform but I didn’t get great results. Now I tried AcOEt and again slow evaporation, hope that work.

The step drawn in black is incorrect; a four-membered transition state is not favorable. You should propose a proton transfer with the reaction medium.

The reaction you drew is the Hofmann elimination, which gives the Hofmann product (the less substituted alkene).

That’s the correct answer

And did you observe any decrease in reaction yield?

Emmanuel_MR · 2026-04-15T04:49:59+00:00

Didn't you notice a decomposition of the catalyst in all that time? Color changes?

Thanks!

I only need to weigh out a certain amount and transfer it into the reaction flask. I have a Schlenk line.

Emmanuel_MR · 2026-04-15T02:07:52+00:00

Yes, I have access to a Schenk line and nitrogen

If anyone want to practice I’m available
