Physical Chemistry


  1. 1.

    The kinetics of the oxidation of 2-aminoethanethiol, 3-aminopropanethiol, 4-aminobutanethiol, (dimethylamino)ethanethiol, and 2-mercaptoethanol by the 1,10-phenanthroline complex [Fe(phen)3]3+ were studied. The complex [Fe(phen)3]3+ only reacts with thiols containing a deprotonated mercapto group.

  2. 2.

    The stoichiometry and the reaction products in the 2-aminoethanethiol + [Fe(phen)3]3+ +oxygen system were studied.

  3. 3.

    2-Sulfo-1-ethanethiosulfuric acid can be used as reagent for thiyl radicals.

  4. 4.

    The differences between the processes occurring in the thiol+[Fe(phen)3]3++O2 system at pH > 1.5 and the reactions in which RS. radicals participate during radiolysis of the thiols in the presence of oxygen were determined.
