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 %).

系统地研究了路易斯或布朗斯台德酸助催化剂在金催化的反应中的影响,使用了代表性的反应(炔烃中的O,N和C亲核加成)。通过这些反应,证明了酸性助催化剂可以显着提高催化剂的转化率,从而在竞争性催化剂负载量(<1 mol%)下实现实用的反应速率。目前正在进行进一步的研究,以增进对这些实验观察的微妙原理的理解。
