C2F5-substituted pyrazolines were synthesized by [3+2]-cycloaddition between in-situ-generated C2F5CHN2 and electron-deficient alkenes. The addition of DBU led to the elimination of HF to give CF3CHF-substituted pyrazoles. Depending on the structure of the pyrazolines, different products were obtained.
