A new direction: The nucleophilic ortho-propargylation of aryl sulfoxides exploits intermolecular delivery of the nucleophile to sulfur followed by an intramolecular relay to carbon (see scheme). The simple, metal-free procedure is general, regiospecific with regard to the propargyl nucleophile, and completely selective for products of ortho-propargylation over allenylation.
