Tautomerism and self-conversion of substituted 2-thiophenethiols. Substituent effects and self-thiylation mechanism

The substitutent effect on the self-thiylation of 2-thiophenethiols was studied. Experimental results and quantum chemical calculations suggested possible mechanisms for this reaction dependent on the reaction conditions.Irkutsk Institute of Organic Chemistry, Siberian Branch, Academy of Sciences of Russia, 664033 Irkutsk, Russia.
