Merging gold catalysis and haloethynyl frames: emphasis on halide-shift processes

Abstract

Haloalkynes can enter a wide variety of metal-catalyzed transformation giving rise to the formation of products with or without showing halide-shift. This article offers an overall view of the reactivity of these substrates under gold catalysis. Particular attention is devoted to intramolecular reactions that involve a concomitant halide-shift process for the case of alkynyl iodides as starting materials.
