The Bray Liebhafsky reaction is a chemical clock first described by William C. Bray in 1921 and the first oscillating reaction in a stirred homogeneous solution. ref cite journal doi 10.1021 ja01439a007 year 1921 author Bray, William C. journal Journal of the American Chemical Society volume 43 pages 1262 issue 6 ref He investigated the role of the iodate IO sub 3 sub sup sup , the anion of iodic acid in the catalytic conversion of hydrogen peroxide to oxygen and water by the iodate. He noticed that the concentration of iodine molecules oscillated and that oxygen did build up pulsating. An increase in temperature reduces the cycle in the range of hours. This oscillating reaction consisting of free radical on non radical steps was investigated further by his student Herman A. Liebhafsky, ref cite journal doi 10.1021 ja01352a006 year 1931 last1 Bray first1 William C. last2 Liebhafsky first2 Herman A. journal Journal of the American Chemical Society volume 53 pages 38 44 ref hence the name Bray Liebhafsky reaction. During this period, most chemists rejected the phenomenon and tried to explain the oscillation by invoking heterogeneous impurities. A fundamental property of this system is that hydrogen peroxide has a redox potential which enables the simultaneous oxidation of iodine to iodate 5 H sub 2 sub O sub 2 sub I sub 2 sub 2 IO sub 3 sub sup sup 2 H sup sup 4 H sub 2 sub O and the Redox reduction of iodate back to iodine 5 H sub 2 sub O sub 2 sub 2 IO sub 3 sub sup sup 2 H sup sup I sub 2 sub 5 O sub 2 sub 6 H sub 2 sub O Between these two reactions the system oscillates causing a concentration jump of the iodide and the oxygen production.

In organic chemistry , an electrophilic aromatic halogenation is a type of electrophilic aromatic substitution . This organic reaction is typical of aromatic compounds and a very useful method for adding substituents to an aromatic system. Image OChem Reaction HalogenationBenzene.png 400px Halogenation of Benzene where X is the halogen, catalyst represents the catalyst if needed and HX represents the protonated base. A few types of aromatic compounds, such as phenol , will react without a catalyst , but for typical benzene derivatives with less reactive substrates, a Lewis acid catalyst is required. Typical Lewis acid catalysts include AlCl sub 3 sub , FeCl sub 3 sub , FeBr sub 3 sub , and ZnCl sub 2 sub . These work by forming a highly electrophile electrophilic complex chemistry complex which attacks the benzene ring. Reaction mechanism The reaction mechanism for chlorination of benzene is the same as bromination of benzene. iron III bromide Ferric bromide and iron III chloride ferric chloride become inactivated if they react with water, including moisture in the air. Therefore, they are generated by adding iron fillings to bromine or chlorine.
