A reinvestigation of the oxidation of cysteine by Br2–˙ and I2–˙. Evidence for CyS ∴ Br– and CyS ∴ I–

John E. Packer  

Abstract

The existence of the species CyS ∴ Br– and CyS ∴ I–, which may be regarded as complexes between the thiyl radical from cysteine and bromide or iodide ions, is reported, and their properties discussed in relation to other sulphur- and halogen-containing species which also have a three-electron half-order bond. The oxidation of cysteine by I2–˙ is shown to be much more complex than hitherto reported, and pH-dependent equilibria involving iodine atoms, iodide ions, cysteine, and cysteinyl radicals are described. The first measured rate constant for the reaction of iodine (as I3–) with a thiol is also reported.
