Coupling with acrylates followed a process of diolefination and a subsequent aza-Michael cyclization. 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\">Safety of 3-(4-Bromophenyl)-1H-pyrazole<\/a>).<\/p>\n<p>3-(4-Bromophenyl)-1H-pyrazole (cas: 73387-46-9) belongs to pyrazole derivatives.
