Iodine monobromide Usage And Synthesis

Chemical Properties

A dark grey to brownish-black crystalline mass that can be dissolved in ethanol, ether, chloroform, carbon disulphide, and other solvents. When it is heated, it becomes partially dissociated. It can prepared by the action of iodine with bromine in a stream of nitrogen. It is used in organic synthesis.

Uses

Iodine monobromide is used as an electrophile employed in a new synthetic approach to polyketide structural units. It is also used in iodometry and serves as a source of I+. It is a powerful iodinating agent used in organic synthesis as well as involved in the synthesis of radioiodinated fatty acids for heart imaging.

Preparation

Prepared from the elements, excess Br is removed by heating to 50 °C in a current of CO2.

Hazard

Toxic by ingestion and inhalation, vapors corrosive to tissue.

Health Hazard

Vapors of iodine monobromide are irritatingto the skin, eyes, and mucous membranes.Its concentrated solutions are corrosive to theskin. Toxicity data for this compound are notavailable.

Fire Hazard

Noncombustible solid. The molten salt ex plodes when mixed with potassium, and ignites with finely divided aluminum. Its mixture with sodium explodes on impact. The reaction of phosphorus with molten salt is violent.

Purification Methods

The brown-black crystals are purified by repeated fractional crystallisation from its melt. The vapour dissociates on heating [Yost et al. J Amer Chem Soc 55 552 1933, Schmeisser in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I pp 291-292 1963].

Precautions

corrosive solid and vapor; readily absorbed through skin and mucous membranes; use in a fume hood and wear gloves and appropriate protective clothing; air-, moisture-, and light-sensitive; should be stored refrigerated (under N2) in a tightly sealed amber bottle. Forms explosive mixtures with potassium and sodium, and reacts extremely exothermically with phosphorus and tin.
