The electrophilic [Ph3PAu]NTf2 quickly diaurates aryl boronic acids providing stable geminally diaurated complexes (see example; yellow, Au; orange, P; blue, C) that have been spectroscopically, and in some cases crystallographically, characterized. Geminally diaurated arenes are putative intermediates in gold(I) catalysis and are analogues of Wheland intermediates of electrophilic aromatic substitutions
