Av. Kalinin et al., FORMATION OF NITROHYDRAZONES BY ACIDIC NITRATION OF ORGANIC HYDRAZINEDERIVATIVES, Russian chemical bulletin, 42(4), 1993, pp. 700-703
It was found by means of NMR spectroscopy that the nitration of trinit
roethyl hydrazine derivatives affords nitrohydrazones rather than nitr
ohydrazines as supposed previously.
