The 13 C NMR spectra of a number of 2,3-dihdyro-1,4-diazepinium salts, like 1 H NMR spectra, confirm shape, and charge distribution for these compounds. The ring has a half-chair shape which is inverting rapidly at room temperature. The atoms in the

Bromination at the 6-position of 2,3-dihydro-1,4-diazepinium salts 1 or at the p-position of a 6-phenyl substituent is subject to steric hindrance, not only by substituents at vicinal sites in the ring(s), but also by substituents at the 1-, 2-, and

A variety of 6-aryldihydrodiazepinium salts (including also 6-biphenyl-4-yl, 6-α-naphthyl, and 6-N-pyridyl) has been prepared, mostly by reactions of 1,2-diamines with 3-aryl-1,5-diazapentadienium salts. The electron-rich dihydrodiazepinium cation a
