Abstract

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 ; This work was supported by grants from the European Research Council (Starting Grant Project ERC-2011-StG-277801), Spanish MINECO (CTQ2013-43012-P to XR, CTQ2015-64436-P to TP, Consolider-Ingenio CSD2010-00065 and INNPLANTA project INP-2011-0059-PCT-420000-ACT1) and Generalitat de Catalunya (2014 SGR 862)
