applications. This approach enabled double C–H thiolation at the C2 and C3 of the indole in one pot. The mechanism studies suggested the thiolation was realized through the sulfoxonium salt rather than sulfenylcarboxylate.

which 2,3,5-tris(methylthio)thiophene (4a) and tetrakis(methylthio)thiophene (5) could be isolated in modest yield. Prolonging the reaction time gave (4a) and 5 in isolated yields of 21 and 16% respectively. Carrying out the same reaction in a sealed autoclave at 150°C with an air overpressure resulted in a clean and rapid (5 h) conversion of thiophene to the tetramethylthio-derivative 5 in moderate isolated
