Abstract Upon the study of powerful insecticidal and fungicidal properties of 1- phenylcarbamoyl-2-pyrazolines and 1, 2, 4-triazoles compounds, a variety of novel 4-(1, 2, 4- triazol-1-yl)-pyrazolines and their derivatives were prepared in good yields. The structures of these compounds were confirmed with 1H NMR, MS, IR and elemental analyses.
