Does the amine oxidize directly or does selenoleum first undergo a quiet, non-redox reaction to form e. g. a selenamide, which later undergoes an
explosive internal redox reaction whether left in selenoleum or separated?
The sources that discuss H2SSeO7 discuss H2SO4 with a small admixture of SeO3. What would be
interesting is the behaviour in the region of 40 % H2S2O7 / 60 % H2Se2O7. Does it
have a melting point maximum with a distinct crystal structure? |
