Nitrogen Trichloride
Nitrogen trichloride is produced from polychlorinated cyanuric acid (TCCA, NaDCC) at acid pH and mainly when the solid product is wet. The cleavage
of cyanuric ring by nucleofiles (like OH-) is known. Once cleaved it form a chloroamine and from here the road to NCl3 is obvious. However this
reaction does not occur in acidic medium and therefore the formation of NCl3 directly from cyanuric ring is probably occurring by another mechanism.
Does anybody know it (with references if possible)?

TCCA is N.N.N- trichloroisocyanuric acid. It readily hydrolyzes to liberate chlorine and isomerizes to cyanuric acid. The ring does not fall apart. In
fact it can be readily rechlorinated to TCCA.
The reaction you are describing strikes me as far fetched. So I'll ask you for your references.

Here's a preparation of NCl3 and it has naught to do with TCCA. The stuff is as you would expect extremely unstable and unsafe to handle except in
dilute solution <16% in chloroform and CCl4.
