The construction of diaryl sulfides through the cross-coupling of aryl iodides and thiols in microwave heating is described. By using this method, a variety of diaryl sulfides can be prepared in a mild condition and in high yields. Deactivated 4-nitrothiophenol was effective to afford the product in 94% yield. Sterically hindered ortho-substituted aryl iodides or thiophenols provided diaryl sulfides effectively by this microwave-assisted coupling reaction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
