摘要：

The reactions of N-nitropyridinium nitrate (1) and 2,6-dideuterio-N-nitropyridium nitrate (2.6-d(2)-1) with SO(2)xH(2)O-HSO3- have been studied. The results are consistent with a reaction scheme in which the formed N-nitro-1,.4-dihydro-4-pyridinesulfonic acid (2) did not react directly to give 3-nitropyridine but existed in equilibrium with 1 and 2,6-d(2)-1 from which N-nitro-1,2-dihydro-2-pyridinesulfonic acid (3) was formed. From 3, 3-nitropyridine was formed by a [1,5] sigmatropic shift of the nitro group.
