Alkyl‐substituted diynes deliver benzofulvenes in a unique gold‐catalyzed reaction. The catalytic cycle involves the formation of gold acetylides by alkynyl C–H activation, the formation of vinylidene gold(I) intermediates by dual activation, and alkyl C–H activation by the vinylidene gold(I) species. gem ‐Diaurated species obtained from the catalysis reactions prove to be highly active catalysts for these conversions.
