Impurity -> Grignard?

[Bwiti]

I dried my THF over NaOH for about a week, then decanted it off into a dry bottle with a teflon screw-cap. After doing this, I noticed that a small amount of NaOH particles came over with it. Will this adversely effect a Grignard rxn?

As OH^- is way more acidic than R^-, any hydroxide ions in the THF will consume one equivalent of grignard reagent. I suggest that you distill it before use, or you might get problems starting the reaction (unless you are making MeMgI or any other very reactive grignard).

I'm planning on using bromobenzene, so I'll have to distill. Thanks for the heads-up.
