Notes:
13C and 15N NMR data are reported for two substituted nitronaphthalenes 1,8-bis(4-toluenesulphonamido)-2,4,7-trinitronaphthalene and 1,8-bis(4-toluenesulphonamido)-2,4,5,7-tetranitronaphthalene and their salts with 1,8-dimethylaminonaphthalene. The salts are shown to contain NHN+ and NHN- intramolecular hydrogen-bonded systems in CD3CN solutions, in agreement with x-ray diffraction data on solid samples and 1H NMR studies on solutions. Examples are given of both a symmetrical and an unsymmetrical bonding system for the NHN atoms. 15N NMR is shown to be particularly helpful in these studies, both 15N shielding and 1J(15N, 1H) couplings are of value. Additional assistance is obtained from 3J(13C9, N1H) data. © 1996 John Wiley & Sons, Ltd.
