(Figure Presented) Thermal decarboxylation of 1-phenyl pyrazolium-3- carboxylates from the mesomeric betaine class of substances leads to pyrazole-N-heterocyclic carbenes, which immediately rearrange to multiply substituted 4-aminoquinolines (see scheme). These species are of interest for the synthesis of heterocycles and pharmacologically active compounds.
