摘要:

AbstractThe synthesis of some novel N‐1 substituted 4‐iodo‐ and 3,4‐diiodopyrazoles starting from the corresponding NH‐pyrazoles is described. On basis of their13C nmr data and those of already known related congeners the influence of iodo‐ as well as N‐1 substituents on pyrazole13C chemical shifts and13C,1H spin coupling constants is
