The synthetic utility of 3-thioaryne intermediates has been demonstrated through an aryne relay approach. The efficient synthesis of o-silylaryl triflate-type 3-thioaryne precursors has been achieved by the regioselective silylthiolation of 3-(triflyloxy)

An efficient method to generate aryne intermediates from o-iodoaryl triflates triggered by triethylsilane and cesium fluoride is disclosed. This method realized the acylalkylation of arynes using easily available o-iodoaryl triflate-type precursors, which was difficult when using conventional nucleophilic activators. A wide range of (hetero)arenes including various fused benzothiazoles were successfully synthesized from o-iodoaryl triflates by virtue of their good accessibility and divergent transformations of aryne intermediates.

A novel method for preparing a diverse range of o-sulfanylanilines is described. Direct thioamination of arynes with sulfilimines gives o-sulfanylanilines, involving C-N and C-S bond formations and migratory N-arylation.
