Tribromide is the anion with the chemical formula Br 3 −, or salts containing it: . Tetrabutylammonium tribromide; Tetrabromophosphonium tribromide; Pyridinium perbromide; Sodium and potassium tribromides can be prepared by reacting NaBr or KBr with aqueous bromine.
Iodine monobromide is an interhalogen compound with the formula IBr. It is a dark red solid that melts near room temperature. [1] Like iodine monochloride, IBr is used in some types of iodometry. It serves as a source of I +. Its Lewis acid properties are compared with those of ICl and I 2 in the ECW model. It can form CT adducts with Lewis ...
It can be made from the elements at low temperature, or from iodine pentoxide and hydrogen chloride. It reacts with many metal chlorides to form tetrachloroiodides (ICl − 4), and hydrolyses in water. The molecule is a planar dimer (ICl 3) 2, with each iodine atom surrounded by four chlorine atoms. Iodine tribromide (IBr 3) is a dark brown liquid.
It is formed by the reaction of indium and bromine. [4] InBr 3 forms complexes with ligands, L, InBr 3 L, InBr 3 L 2, InBr 3 L 3. [3]Reaction with indium metal forms lower valent indium bromides, InBr 2, In 4 Br 7, In 2 Br 3, In 5 Br 7, In 7 Br 9, indium(I) bromide.
Iodine monochloride and iodine monobromide may be prepared simply by reacting iodine with chlorine or bromine at room temperature and purified by fractional crystallisation. Both are quite reactive and attack even platinum and gold, though not boron, carbon, cadmium, lead, zirconium, niobium, molybdenum, and tungsten. Their reaction with ...
Gold(III) bromide catalyzes a variety of reactions. In one example, it catalyzes the Diels-Alder reaction of an enynal unit and carbonyl. [14] Another catalytic use of gold tribromide is in the nucleophilic substitution reaction of propargylic alcohols. In this reaction, the gold complex serves as an alcohol-activating agent to facilitate the ...
