This is a neat little structure, and it’s truly a pain to synthesize (12 steps from myo-inositol). But it now seems to hold the record as the most polar aliphatic compound ever measured, and well it might. David O’Hagan of St. Andrews reported it at the ACS meeting in Denver – one side of that molecule is full of electronegative fluorines, and the other side has what’s left. In bulk, this would be a very unusual solvent to play around with in chromatography and the like, but I don’t think we’re going to see any four-liter jugs of around the lab any time soon.
Update: annoyingly for my speculations, the compound appears to be a solid. Maybe the smaller-ring analogs?
