Abstract

One-electron oxidation of thiols by oxidizing radicals leads to the formation of thiyl and carbon-centered radicals [1-3]. It has been shown experimentally that in the absence of oxygen, the thiyl radicals derived from certain thiols of biological interest such as glutathione, cysteine and homocysteine decay rapidly by intramolecular rearrangement reactions into the carbon-centered radical [4-6]. In the present work we have investigated theoretically the structure and the stability of thiyl and carbon-centred radicals of homocystein in order to check the possibility of this rearrangement.
