Pyrazoline sind in der Chemie eine Stoffgruppe von Heterocyclen mit der Summenformel C3H6N2.
| Isomere Pyrazoline |
|---|
| 1-Pyrazolin |
| 2-Pyrazolin |
| 3-Pyrazolin |
Die Bezeichnung ist ein veralteter Trivialname fΓΌr die Gruppe der Dihydropyrazole. AbhΓ€ngig von der Position der Doppelbindung im Heterocyclus unterscheidet man die folgenden Isomeren:
β’ 1-Pyrazolin (heutiger IUPAC-Name: 4,5-Dihydro-3H-pyrazol)cite-ref-1[S 1]
β’ 2-Pyrazolin (heutiger IUPAC-Name: 4,5-Dihydro-1H-pyrazol) undcite-ref-2[S 2]
