1-phenyl-2-thiourea
« on: February 09, 2003, 12:58:00 AM »
Does anyone have the time to ponder whether something useful could be done with 1-phenyl-2-thiourea?

I had in mind this unwatched compound being reacted in such a way that the yield would be bromobenzene + by products.

In a similar fashion, I wonder whether 1-allylthiourea could yield somehow allylbromide/allylchloride/allyliodide?

See what I'm getting at here?

followed by grignard reagent
