Sulfur dibromide readily decomposes into S2Br2 and elemental bromine. In analogy to sulfur dichloride, it hydrolyzes in water to give hydrogen bromide, sulfur dioxide and elemental sulfur.
SBr2 can be prepared by reacting SCl2 with HBr, but due to its rapid decomposition it cannot be isolated at standard conditions. Instead, the more stable S2Br2 is obtained.[1]
