2-mercaptoimidazole derivatives with a series of with differently substituted iodobenzenes and iodothiophenes at 100 °C is described. This method proceeds efficiently without ligands and at lowcatalystloading (3 mol %), without the need for stringent inert conditions. Under optimized conditions, the S-arylated products were obtained in good yields of up to 90%.
