Reactions of S 4 N 4 include some in which the ring is preserved when groups are added to S or N as well
as some in which the ring is changed into one having a different number of atoms. Other reactions
lead to complete disruption of the ring, so there is a very broad chemistry of this interesting molecule.
In halogenation reactions with Cl 2 and Br 2, the product, S 4 N 4Cl 4, retains the ring structure of S 4 N 4 ,
and the chlorine atoms are bonded to the sulfur atoms.
