Comments like "Pentaborane is 2,000 times more deadly than cyanide" are just nonsense.
I was told one of the boranes were 2,000 times more deadly than HCN. Diborane?
You'd just about get away with sniffing Pentaborane (as long as it didn't explode in your face), but I wouldn't like to try that again with cyanide. Did it once, nearly got killed.
I guess you're right.
There would probably have been more success with an organoborane (e.g. Methylborane) dissolved in a synthetic hydrocarbon, but they don't seem to have explored that very far.
Why haven't they assuming it's not classified?
