Sulfur dibromide

Sulfur dibromide is the chemical compound with the formula SBr. It is a toxic gas.
Sulfur dibromide readily decomposes into SBr and elemental bromine. In analogy to sulfur dichloride, it hydrolyzes in water to give hydrogen bromide, sulfur dioxide and elemental sulfur.
SBr can be prepared by reacting SCl with HBr, but due to its rapid decomposition it cannot be isolated at standard conditions. Instead, the more stable SBr is obtained.
