The ionic liquid was easily separated from the reaction mixture and was recycled and used for at least six consecutive runs without any loss of activity. In the experiment, the researchers used many compounds, for example, 3,5-Dimethyl-1H-pyrazole-1-carboxamide (cas: 934-48-5<a href=\"https:\/\/www.ambeed.com\/products\/934-48-5.html\">Application In Synthesis of 3,5-Dimethyl-1H-pyrazole-1-carboxamide<\/a>).<\/p>\n<p>3,5-Dimethyl-1H-pyrazole-1-carboxamide (cas: 934-48-5) belongs to pyrazole derivatives. As is the case with imidazoles, the pyrazole ring offers many opportunities to create new multiring systems that incorporate this heterocycle. The presence of both electronegative nitrogen atoms in the pyrazole ring reduces the electron density of the C3- and C5-positions leaving electron density of C4-position unaltered. Thus the C4-position is vulnerable to electrophilic attack. The C3 electrophilic-position may undergo deprotonation in the presence of a strong base leading to ring opening.<a href=\"https:\/\/www.ambeed.com\/products\/934-48-5.html\">Application In Synthesis of 3,5-Dimethyl-1H-pyrazole-1-carboxamide<\/a><\/p>\n<p>Referemce:<br \/><a href=\"https:\/\/en.wikipedia.org\/wiki\/Pyrazole\">Pyrazole &#8211; Wikipedia<\/a>,<br \/><a href=\"https:\/\/www.sciencedirect.com\/topics\/chemistry\/pyrazoles\">Pyrazoles &#8211; an overview | ScienceDirect Topics<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>3,5-Dimethyl-1H-pyrazole-1-carboxamide (cas: 934-48-5) belongs to pyrazole derivatives.
