In organic synthesis it is used as a reagent and as a catalyst, either on its own or as a complex with nitrogen or sulfur ligands.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSandmeyer bromination.\u003c\/strong\u003e In the Sandmeyer reaction, CuBr converts arenediazonium salts into aryl bromides. The diazonium salt is formed from an aromatic amine with sodium nitrite in hydrobromic acid and is then treated with CuBr, which replaces the diazonium group with bromine. The method gives substituted aryl bromides from the corresponding anilines. A catalytic version uses copper(I) and copper(II) with 1,10-phenanthroline as the ligand.\u003c\/p\u003e\n\u003cdiv style=\"margin:8px 0 18px 0;\"\u003e\n\u003cdiv
