4-Nitropyrazolin-5-ones have been synthesized by the nitration of pyrazolin-5-ones at room temperature by employing the Fe(NO3)3/NaNO2 system. The method demonstrated selectivity towards the 4-position of pyrazolin-5-ones

Pyrazolin-5-ones (3a-i) were oxidized with 2,4,6-trisubstituted phenoxy radicals (2a-d) to the corresponding radicals (4a-i), which dimerised or combined with phenoxy radical (2a) depending on the R1- and R4-substituents in (3).In th
