M. Brisander et al., DIAZEPINES - PART 30 - A COMPARISON BETWEEN THE EXTENT OF DELOCALIZATION OF ELECTRONS IN A VINAMIDINE AND ITS PROTONATED FORM - CRYSTAL ANDMOLECULAR-STRUCTURE OF 2 2,3-DIHYDRO-1,4-DIAZEPINES, Journal of chemical research. Synopses, (2), 1998, pp. 72
An X-ray study of two 2,3-dihydro-1,4-diazepine bases shows that their
vinamidine systems are made up of alternate single and double bonds,
in contrast to the derived monocations which contain fully delocalised
vinamidinium structures.
