Interhalogen compounds iodine monochloride

Interhalogen compounds such as iodine monochloride have been added to fluoroalkyl-substituted alkenes. The observed unidirectional regiochemistry can be explained by the polarity ot the double bond [14] (equation 7)... 

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]. 

The halogenation of a wide variety of aromatic compounds proceeds readily in the presence of ferric chloride, aluminum chloride, and related Friedel-Crafts catalysts. Halogenating agents generally used are elemental chlorine, bromine, or iodine and interhalogen compounds (such as iodine monochloride, bromine monochloride, etc.). These reactions were reviewed554 and are outside the scope of the present discussion. 

The reactions of the interhalogen compounds are not greatly different from those of the halogens themselves. Hydrolysis of compounds in basic solution yield the halide ion derived from the smaller halogen and an oxy-halogen anion derived from the larger halogen thus, hydrolysis of BrF yields a 5 1 mixture of fluoride and bromate, Iodine monochloride... 

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.
