Know How to Make 3,4 Difluorothiophene?
Here's an interesting challenge: over at Synthetic Remarks, there's a need for a couple of grams of 3,4-difluorothiophene. But you can't buy that much, and the literature has very little useful to say about how one would make it. So is there a practical route to the stuff (at least on paper) that's worth trying? Note that Dr. Freddy stipulates "No Sandmeyer crap, for heaven's sake", so no Balz-Schiemann chemistry, folks.
The prize? Any chemistry book worth up to $150 from Amazon, sent to your door. (Just think of the possibilities) So if any of you have any bright fluorination ideas, have a crack at it, and good luck!
