摘要：
The synthesis of some novel N-1 substituted 4-iodo- and 3,4-diiodopyrazoles starting from the corresponding NH-pyrazoles is described. On basis of their C-13 nmr data and those of already known related congeners the influence of iodo- as well as N-1 substituents on pyrazole C-13 chemical shifts and C-13,H-1 spin coupling constants is investigated.
