Title
Gold-catalyzed cyclotrimerization of arynes for the synthesis of triphenylenes
Abstract

•A novel and efficient Au(I)-catalyzed cyclotrimerization of arynes was found.•The cyclotrimerization of arynes affords triphenylenes under mild conditions.•The cyclotrimerization of arynes was neither air nor moisture sensitive.

A novel and efficient Au(I)-catalyzed cyclotrimerization of arynes, generated by fluoride-induced elimination of Kobayashi's silylaryl triflates, is described. The reactions led to the formation of triphenylenes in 45–88% yields under mild conditions. © 2015 Elsevier B.V. All rights reserved.
