salts is described starting from N-trimethylsllylimines of aromatic ketones. Molecularstructures and charge distributions of the linear allenoid and the angular allylic forms of monosubstituted 2-aza-allenium cations are calculated by the semiempirical MINDO/3 method. The u.v. spectra of tetraaryl-2-aza-allenium cations have been measured and interpreted by theoretical transition energies obtained
