Polystyrene‐immobilized cationic gold catalysts 2a and 2b were synthesized for the first time and found to be highly effective catalysts for the bond‐forming reactions via the activation of the CC triple bonds. The immobilized 2a was easily and quantitatively recovered from the reaction mixture and reused at least seven times while maintaining the original catalytic activity. Furthermore, a flow reactor containing 2a was developed for a larger scale continuous production.
