Die Beziehungen zwischen dem Indazol1) und dem Anhydrid der o-Hydrazinobenzoesaure2), welche aus den Structurformeln abgeleitet werden konnen, sind bisher experimentell nicht gepruft worden. Diese Lucke wird durch nachfolgende Versuche ausgefullt, welche zugleich eine bequeme Darstellung des bisher schwer zuganglichen Indazols aus der jetzt sehr ...

Importance of Indazole against Neurological Disorders
Current Topics in Medicinal Chemistry, 2022Abstract: Indazole is a nitrogen-containing bicyclic compound, having three tautomeric forms: 1Hindazole, 2H-indazole, and 3H-indazole. Mostly, they are considered as 1H-indazole tautomeric forms, although they have the potential to tautomerism to 2H- and 3H-indazole forms. Indazoles are involved in a wide variety of biological and enzymatic processes.

Vibrational Spectra of Indazole
Spectroscopy Letters, 1990Abstract The i.r. spectra of indazole have been measured from 4000 to 180 cm−1; polarized spectra of single crystals have been also obtained. The Raman spectra of polycrystalline samples and solutions have been recorded and the polarization of many lines has been determined. Most vibrations have been assigned on the basis of the i.r.

Fluorinated Pyrazoles and Indazoles
2014The synthesis of fluorine containing pyrazoles has been boosted in the past decades due to the interesting properties that confer these building blocks in pharmaceutical and agricultural active ingredients. There are two main methods for the synthesis of fluorine-containing organic compounds, namely, the direct replacement of an atom or functional ...
