I am trying to figure the cheapest way to brominate 2-pentyn-1-ol.
I first thought Finkelstein may be the way to go via the mesylate. It is two steps though.
Then I thought triphenylphosphosphine and bromine, but it is costly.
Lastly, I thought about Phosphorus Tribromide. Will this work easily for propargly alcohols??
Does anyone have any experience??
This is done neat, right? With pyridine as an HBr scavenger???
