Abstract
Brønsted or Lewis acid assisted activation of an imidogold precatalyst (L-Au-Pht, Pht = phthalimide) offers a superior way to generate cationic gold compared with the commonly used silver-based system. It is also broadly applicable for most common gold-catalyzed reactions. For reactions that require milder conditions, milder acids can be used for optimized efficiency.
摘要
与常用的银基体系相比，布朗斯特或路易斯酸辅助活化亚氨基金预催化剂（L-Au-Pht，Pht = 邻苯二甲酰亚胺）提供了一种生成阳离子金的优越方法。它也广泛适用于大多数常见的金催化反应。对于需要更温和条件的反应，可以使用更温和的酸以优化效率。
