Gold-catalyzed reaction of enynols by a dimerization–fragmentation process: an expeditious assembly of enyne molecular architecture

Intermolecular condensation reaction of 1,3,5-triarylenynols catalyzed by gold as Lewis acid was reported for the first time; the products with unique structures have potential applications in materials chemistry, and tandem reaction product 3n has been used to detect mercury ions as an organic molecular probe.
