Specifications

Description

Applications
Microwave heating of 2-halobenzaldehydes or 2-haloacetophenones with phenylhydrazines at 160°C for 10 min quantitatively yielded the arylhydrazones, which were further cyclized to give 1-aryl-1H-indazoles via CuI/diamine-catalyzed N-arylation under microwave heating (160°C, 10 min). Good to excellent yields were observed for 2-iodo, 2-bromo, and 2-chloro benzaldehydes or acetophenones.

Solubility
Slightly soluble.

Notes
Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Store away from strong oxidizing agents. Refrigerate 2-7°C.
