Au(iii)-aryl species have been unequivocally identified as reactive intermediates in oxidant-free C-O and C-N cross coupling catalysis. The crystal structures of cyclometalated neutral and cationic Au(iii) species are described and their key role in 2 electron-redox Au(i)/Au(iii) catalysis in C-O and C-N cross couplings is shown. Nucleophiles compatible with Au-catalyzed cross couplings include aromatic and aliphatic alcohols and amines, as well as water and amides.
金（III）-芳基物种已被明确鉴定为无氧化剂的碳-氧和碳-氮交叉偶联催化中的反应中间体。描述了环金属化中性和阳离子金（III）物种的晶体结构，并展示了它们在碳-氧和碳-氮交叉偶联的两电子氧化还原金（I）/金（III）催化中的关键作用。与金催化交叉偶联兼容的亲核试剂包括芳香族和脂肪族醇、胺以及水和酰胺。
