Chemical Properties
clear yellow to brown liquid
Uses
1-Phenylpyrazole has been used:
- in the preparation of 4,5-diphenylpyrazolo[1,5-a]quinoline, 1-(1,2,3,4-tetraphenylnaphthalen-5-yl)pyrazole and 1-(1,2,3,4,5,6,7,8-octaphenylanthracen-9-yl)pyrazole
- as cyclometallated ligand in the preparation of new heteroleptic iridium(III) complexes
Definition
ChEBI: A member of the class of pyrazoles that is 1H-pyrazole substituted by a phenyl group at position 1.
General Description
1-Phenylpyrazole undergoes cyclometallation with rhodium trichloride to yield
rac-di(μ-chloro)
tetrakis[2-(pyrazol-1-yl)phenyl-
C1,
N2′]dirhodium. The activation of the C-H bond of 1-phenylpyrazole autocatalyzed by the co-product HOAc was studied.
