A general access to organogold(iii) complexes by oxidative addition of diazonium salts

The light-induced reaction of aryldiazonium salts with gold(i) chloride complexes provides an easy access to cationic or neutral arylgold(iii) complexes, even a bromoaryl group can be selectively installed at gold(iii), and either chelating or monodentate ligands can be used.
