The photolysis of different nitro 3H-pyrazoles, obtained indirectly from nitroethylenes, is studied.Inter and intramolecular processes to stabilization are observed with conservation of the nitro group in the case of an α-nitro vinylcarbene.On the contrary the β-nitrocarbene reacts to give α-oximinoketones.
