摘要
AM1 calculations show 2-nitraminopyridine to contain 97.7 % of 1,2-dihydro-2-nitriminopyridine form which was found to be the most stable in the gas phase. Except the proton transfer processes, dimerization was also found to appear in this compound. Instead, non-planar nitramine form was found to dominate for 4-nitraminopyridine. The results are related to experimental (X-ray and N-15 NMR) data. (C) 1997 Published by Elsevier Science Ltd.
