The cross‐dehydrogenative coupling of terminal alkynes and hydrosilanes catalyzed by AuPd nanoalloys is described. Metal nanoparticles are readily prepared in 15 minutes from commercially available and cheap starting materials by using a photochemical approach. The ratio of Au and Pd in the alloys heavily influences their reactivity. These cooperative nanoalloy catalysts tolerate a large number of functional groups (e.g., free amines and acids), operate at room temperature under air atmosphere at low loading (2 mol %), and the cross‐dehydrogenative coupling can easily be scaled up.
