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
Bromination of Sydnones. I. Reaction with 3-Arylsydnones Containing Electron-Donors on the Aryl Ring

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.
