This method has the advantages of easier work-up, mild reaction condition, high yields, shorter reaction time, and environmentally benign procedure. In the experiment, the researchers used many compounds, for example, 3-(4-Bromophenyl)-1H-pyrazole (cas: 73387-46-9<a href=\"https:\/\/www.ambeed.com\/products\/73387-46-9.html\">Formula: C9H7BrN2<\/a>).<\/p>\n<p>3-(4-Bromophenyl)-1H-pyrazole (cas: 73387-46-9) belongs to pyrazole derivatives.

The pyrazole ring is resistant to oxidation and reduction but the groups, such as alkyl and formyl attached to the ring, are oxidized to respective acids.
