摘要：

Reaction of alkynyl(p-phenylene)bisiodonium ditriflates (2) with sodium phenoxide in methanol provides 2-substituted benzofurans (3). This result indicates that beta-phenoxyalkylidenecarbenes generated by the reaction with phenoxide anion undergo novel intramolecular aromatic C-H insertion to afford benzofurans.
