- Imination of N-Methylazinium Salts by Liquid Ammonia/Potassium Permanganate
-
Treatment of 1-methylquinolinium-, 1,4-dimethylquinolinium- and 1-methyl-1,X-naphthyridinium iodides (X=5,8) with liquid ammonia/potassium permanganate leads to introduction of the imino group at C-2 forming the 1,2-dihydro-2-imino-1-methylquinolines and 1,2-dihydro-2-imino-1-methyl-1,X-naphthyridines (X=5,8) respectively. 1,2-Dimethylquinolinium iodide, when subjected to treatment with liquid ammonia/potassium permanganate undergoes an oxo-demethylation reaction, yielding 1-methylquinol-2-one.The nmr-measurements of solutions of the above-mentioned salts in liquid ammonia clearly show the formation of ?-adduct, strongly suggesting that these ?-adducts are intermediates in the imination reactions.
