首次合成了聚苯乙烯固定的阳离子金催化剂2a和2b，并发现它们是通过激活CC三键进行成键反应的高效催化剂。固定化的2a很容易从反应混合物中定量回收，并重复使用至少七次，同时保持原有的催化活性。此外，还开发了含有2a的流动反应器用于更大规模的连续生产。
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 C C 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.
