A systematic study on the effects of Lewis or Brønsted acid co‐catalysts in gold‐catalyzed reactions was undertaken using representative reactions (O‐, N‐, and C‐nucleophilic additions to alkynes). Through these reactions, it was demonstrated that an acidic co‐catalyst can increase the catalyst turnover significantly, enabling practical reaction rates at competitive catalyst loadings (<1 mol %).
