N-Phenyl-4-(2-pyridinyl) sydnone was shown to act as a four-electron donor N,O-ligand in unprecedented coordination complexes 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.

Unstable N-heterocyclic carbenes can be masked and stabilized as pseudo-cross-conjugated hetarenium-carboxylates which decarboxylate on warming. This study deals with the decarboxylation of carboxylates of mesoionic compounds to generate anionic N-heteroc

4-Bromo-3-arylsydnones 1 are debrominated to the corresponding 3-arylsydnones 2 in good to excellent yield using sodium sulfite in methanol/water.In contrast to previously employed reagents, the reaction is successful in the presence of electron-donating,
Bromination of Sydnones. I. Reaction with 3-Arylsydnones Containing Electron-Donors on the Aryl Ring
Turnbull, Kenneth
, p. 965 - 968 (2007/10/02)
Bromination has been examined for a series of 3-arylsydnones (1) with electron donors (dimethyl to dimethoxy) on the aryl ring.In no example was exclusive aryl ring bromination observed, however, exclusive sydnone ring bromination could be realized in every case.For two dimethoxyphenyl examples both aryl and sydnone ring bromination occurred.
