    Description / Table of Contents: α-Halo-substituted Amines, XXX. Carbimonium Chlorides Containing Aromatic or Heterocyclic Substitutents in α-PositionThe carbimonium salts 2A-D D and 5A-C which contain an aromatic or heterocyclic substituent, are obtained by cleavage of the corresponding aminals with acetyl chloride. The u.v. spectra of the carbimonium salts are measured and the rates of the hydrolyses leading to the corresponding aldehydes are determined by photometric technique.
    Notes: Die durch aromatische bzw. heterocyclische Reste substituierten Carbimoniumsalze 2A-D und 5A-C wurden durch Spaltung der zugehörigen Aminale mit Acetylchlorid dargestellt, ihre Absorptionsspektren gemessen und die Geschwindigkeiten der zu den entsprechenden Aldehyden führenden Hydrolysen photometrisch ermittelt.

    Description / Table of Contents: α-Halogenated Amines, XXXV Bis-carbiminium- and Carbiminium-amidinium-halidesWith acyl halides dialdehyd-bis-aminals 1, 3 or 5 undergo cleavage to bis-carbiminium halides 2, 4 and 6. Reaction of bromine with 1.1.2-triaminoethenes 8 affords carbiminium-amidinium bromides 9.
    Notes: Dialdehyd-bis-aminale, wie 1, 3 oder 5, werden durch Carbonsäurehalogenide unter Bildung der Bis-carbiminium-halogenide 2, 4 und 6 gespalten. Aus 1.1.2-Triamino-äthenen 8 und Brom entstehen Carbiminium-amidinium-bromide 9.
