Sulfur dibromide readily decomposes into SBr and elemental bromine. Adding ethylene dibromide (EDB) to TEL solved the problem. Both monoallylindium dibromide and diallylindium bromide are produced. The resulting ethylene dibromide was taken from Amlwch by rail as well. Selenium dibromide is a compound made of one selenium and two bromine atoms. The dibromide or dihydrogen product (tetralin) never form. Sulfur dibromide is the chemical compound with the formula SBr. Disulfur dibromide is the inorganic compound with the formula SBr. Thermal isomerisation then gives pseudo-ortho atropisomer of the dibromide. In the first step, [2.2]paracyclophane is dibrominated to give a pseudo-para dibromide. "meso"-Stilbene dibromide is an organic molecule with a net formula of CHBr. They also arise by myriad other methods, e.g., starting from xylylene dibromide (CH(CHBr)). The first such compound was zirconocene dibromide ((CH)ZrBr), reported in 1952 by Birmingham and Wilkinson.
