Beschreibung

5-Chloro-1H-pyrazole is a chlorinating agent that reacts with trifluoromethanesulfonic acid to form a mixture of chloropyridines and pyrazoles. The reaction is completed in the presence of hydrochloric acid, which catalyzes the formation of hydrogen chloride gas. The reaction solution becomes acidic and forms an amorphous solid. 5-Chloro-1H-pyrazole can be synthesized in an asymmetric synthesis by reacting pyrazole with maleic anhydride. The chloro group can be removed by oxidation or hydrolysis to produce an amide or n-oxide. The nmr spectrum of 5-chloro-1H-pyrazole contains signals at δ 4.0 (CHCl), δ 2.6 (CCl), δ 1.8 (CHCl) ppm. Pyrazoles are compounds that contain a ring composed of three carbon atoms and
