The reduction of different 2-azolyl-and azinylisoquinolinium salts with sodiumborohydride in methanol was studied. Surprisingly, contrary to what is found in the literature 1,2-dihydroisoquinoline derivatives were obtained. Their formation was attributed to the electron withdrawing character of the heterocyclic ring in position 2 of the isoquinolinium moiety. This was corroborated by synthesis and
