Reactivity studies reveal unprecedented two-electron reduction ability of dinuclear Au(0) complex, suggesting new pathways in gold chemistry.
Despite significant advances in gold chemistry, the synthesis and stabilization of gold centers in a low oxidation state, particularly dinuclear Au(0) species, remain a considerable challenge. In this work, we report the successful isolation of a novel dinuclear Au(0) complex stabilized by tridentate P–Mg–P ligands. Computational studies demonstrate that the Au(0)–Au(0) σ‐bond acts as a two‐electron donor to the Mg centers. Reactivity studies further revealed the complex's unprecedented ability to perform two‐electron reductions on a range of substrates, akin to the behavior of well‐established Mg(I) and Zn(I) dimers.
