• Gold( ii ) complexes, unlike their gold( i ) and gold( iii ) counterparts, have been sparsely employed in the field of catalysis. This is primarily due to the challenges associated with isolating and characterising these open-shell species. However, these complexes offer a wide range of possibilities. On one hand, this intermediate oxidation state has proven to be more easily accessible through reduction and oxidation processes compared to the gold( i )/gold( iii ) redox couple, thereby facilitating potential homo-coupling and cross-coupling reactions. On the other hand, gold( ii ) exhibits Lewis acid behaviour, bridging the characteristics of the soft acid gold( i ) and the hard acid gold( iii ). In this review, we focus on mono- and dinuclear gold( ii ) complexes, whether they are isolated and well-studied or proposed as intermediates in cross-coupling reactions induced by the action of oxidants or light. We delve into the unique reactivity and potential applications of these gold( ii ) species, shedding light on their role in this field. This comprehensive exploration aims to underscore the latent promise of gold( ii ) complexes in catalysis, offering insights into their structural and mechanistic aspects while highlighting their relevance in contemporary chemical transformations. This perspective highlights the potential of gold( ii ) complexes in catalysis, shedding light on the pivotal roles played by mononuclear and dinuclear gold( ii ) complexes, whether as isolated entities or proposed intermediates, in catalytic reactions.
