A disilathiane was found to be a novel S1 source for the copper-catalyzed synthesis of diaryl sulfides using aryl iodides. The reaction of iodoarenes and hexamethyldisilathiane, (Me3Si)2S, in the presence of a catalytic amount of CuI/1,10-phenanthroline provided various types of diaryl sulfides in good yields.
Key words
