Interhalogen compounds iodine monobromide

Interhalogen compounds may lead to product mixtures. The products formed when 1-aminopyrazoles were treated with iodine monobromide were a 17 73 ratio of 4- and 5-bromo derivatives with iodine monochloride there was an 81% yield of the 4-iodo product with only traces of the chloro analogue [86JCS(P 1)1249]. 

Many interhalogen compounds explode on contact with potassium. These include chlorine trilluoride, iodine monochloride, iodine monobromide, iodine pentalluoride, and others. A violent explosion occurs when chlorine monoxide comes in contact with potassium. Potassium bums spontaneously with fluorine, chlorine, and bromine vapor. Its mixture with liquid bromine can explode on impact, and mixture with iodine ignites.

Alkoxyl exchange in redistribution reactions of alkyl alkoxyl silanes is catalyzed by several interhalogen compounds, notably iodine monobromide, and by iodine. Halogen exchange between alkyl halides and trimethylsilicon iodide is also catalyzed in some cases by iodine. ...
