title: Dual gold-catalyzed head-to-tail coupling of iodoalkynes.
abstract: Various haloalkynes are converted in the presence of a dual activation gold catalyst. Via a dual activation process a completely atom economic head-to-tail coupling delivers gem-dihalogenated conjugated enynes as valuable building blocks for organic synthesis.
