Popis:	The diastereoselective Michael addition of the title anion to alpha-hydrogen- and alpha-methyl-substituted conjugated nitroalkenes leads to new gamma-nitrocarbene complexes and gamma-hydroximoamides, respectively. The gamma-nitrocarbene complexes can be quantitatively oxidized to gamma-nitrobutyric acid derivatives (precursors of GABA derivatives); the gamma-hydroximoamides are formed as a result of an unexpected intramolecular transfer of an oxygen atom from the nitro group to the carbene atom, with elimination of the pentacarbonyl-chromium(0) group, which is recovered in high yield as the PyCr(CO)(5) complex
