> What's the name for the compound shown at right? [BrC2O4F3] Very few of us will have the need to name it, though - you make that one by condensing trifluoroacetic anhydride onto the bromyl fluoride at -196C, then warming and recrystallizing the solid from liquified freon to give yellow crystals. Those melt at -12C, and according to the paper and its SI, [...] and "inevitably explodes upon further warming". Further experimentation runs a risk of exposure to further inevitabilities, and I'm glad that Prof. Seppelt's expertise in the lab got him through all this.

Never mind Prof. Seppelt (who conveniently survived to publish his research) - what are the actuaries saying about his grad students, postdocs, and sundry assistants wearing those cheap red lab coats?
