Treatment of 5-nitro-2,4-dihydro-3H-1,2,4-triazol-3-one (1) with picryl fluoride (PkF) in 1-methyl-2-pyrrolidinone (NMP) gave a mixture of a monopicryl and dipicryl derivative of 1 in a ratio of 2:1 , respectively, regardless of the initial concentrations of 1 and PkF.The products were identified as 5-nitro-2-picryl-2,4-dihydro-3H-1,2,4-triazol-3-one (2) by X-ray crystallography and 5-nitro-2,4-dipicryl-2,4-dihydro-3H-1,2,4-triazol-3-one (4) by 15N labeling experiments.
