Abstract

Complete assignment of ^1^H and ^13^C NMR chemical shifts and J(^1^H/^1^H and ^1^H/^19^F) coupling constants for 22 1‐phenyl‐1__H__‐pyrazoles' derivates were performed using the concerted application of ^1^H 1D and ^1^H, ^13^C 2D gs‐HSQC and gs‐HMBC experiments. All 1‐phenyl‐1__H__‐pyrazoles' derivatives were synthesized as described by Finar and co‐workers. The formylated 1‐phenyl‐1__H__‐pyrazoles' derivatives were performed under Duff's conditions.
