Abstract

Previously synthesized 4-nitrosopyrazoles with a perfluoroalkyl substituent containing thienyl, phenyl and naphthalene fragments were reduced to amines with hydrazine hydrate. The Sandmeyer reaction for 4-aminopyrazoles was carried out using 3(5)-(thiophen-2-yl)-4-amino-5(3)-(trifluoromethyl)- 1H-pyrazole as an example. Identification of new compounds was proved by 1H NMR spectroscopy and mass spectrometry
