Reaction products of bicyclo[2.2.1]hept-2-ene-endo, endo-5,6-dicarboxylic (endic) acid with hydrazines and acylhydrazines were prepared. The features distinguishing of these reactions from those with amines were revealed. The compounds obtained were characterized by H-1, C-11 NMR, and IR spectra. The assignment of the signals in NMR spectra was done with the use of quantum-chemical calculations of chemical shifts performed by the density functional method. The structure of one among compounds synthesized, N-(m-hydroxybenzoylamino)-bicyclo[2.2.1] hept-2-ene-endo, endo-5,6-dicarboxamide, was proved by X-ray diffraction analysis.
