N-Phenyl-4-(2-pyridinyl) sydnone was shown to act as a four-electron donor N,O-ligand in unprecedented coordinationcomplexes featuring three different metallic centers (Co, Cu, and Zn). Starting with various anilines, the use of a ball-mill efficiently enabled the synthesis of N-arylglycines, subsequent nitrosylation and cyclization into sydnones, and further metalation.

A series of sydnones was used as N-heterocycliccarbene (NHC) precursors to synthesize gold(I) complexes by a two-step reaction. The first reaction step involves the deprotonation of the sydnone to obtain the corresponding anionic NHC. Second, the metal precursor was added to afford the corresponding gold(I) complex. At this point, the complex obtained depends on the nature of the metal precursor.
