A copper-catalyzed three-component coupling reaction of aryl iodides, hexamethyldisilathiane
and alkyl benzoates leading to alkyl aryl sulfides has been demonstrated. A disilathiane
acted as both a sulfur source and a promoter of the sulfidation, and the alkyl moiety
of the alkyl benzoate was effectively introduced on one side of the sulfide. Moreover,
we found that the protocol can be expanded to the preparation of ethyl phenyl selenide
with diphenyl diselenide.
