Less is More: A highly selective Pd‐catalyzed Csp–Csp cross‐coupling reaction between terminal alkynes and 1‐bromoacetylenes has been developed. Catalyst loading is low (only 0.0001–0.01 mol % of Pd is required) and provides products with high selectivities and good to excellent yields under mild conditions. TBAB=tetrabutylammonium bromide, TON=turnover number.
