2-Pyrazolin-4-oximes have been synthesized by reaction of 4-nitroso-and 4nitropyrazoles with complex metal hydrides and organometallic reagents. Furthermore, 4nitropyrazolium tetrafluoroborates are reactive substrates towards organolithium and Grignard compounds leading to new and highly substituted
