The reaction of 1-amino-2-cyanopyridinium perchlorate (1) with triethyl orthoformate gave an ethyl iminoformate derivative (2) which resulted in formation of a 1-iminopyrido-as-triazinium salt (3) in reaction with primary amine, and a formamidino derivative (4) with morpholine gave 2,3-diaza-1,3,5,7-octatetraene (5). The two benzologues of 1,N-aminoquinolinium (9) and N-aminoisoquinolinium (19) gave ethyl iminoformates (10 and 20) and formamidines (14 and 23). In reactions with primary amines these compounds led to s-triazolo[1,5-a]quinolinium (16) and [5,1-a]isoquinolinium (25) salts, respectively.
