¹³C Nmr study of 1,2,4‐triazino[4,5‐<i>b</i>]indazole derivatives

Abstract

Abstract The main nmr parameters of 1,2,4‐triazino[4,5‐ b ]indazole derivatives were measured on the basis of their 13 C nmr spectral analysis compared to indazole models. 1 J C‐H coupling constants were studied and the correct structure of 1,2,4‐triazino[4,5‐ b ]indazoles was elucidated.
