Nox,
That seems like a great idea. I knew about the Pka, but my problem is that the next step to get the vinyloxirane is to use NaOH as the base and then kicks out the bromine. But as I thought about it, the reaction is done at about 120 °C. So the washing with 1 N NaOH and then back extracting could work. Thank you very much for the insight.
Disco,
You are 100% correct, my time is more valuable. I can recover the CCl4 aswell for future reactions.
