Synthesis and Characterization of Some 3-Acyl-4-amino-1aryl-1H-pyrazoles

Original language description

A series of 3-acyl-4-amino-1-aryl-1H-pyrazoles has been prepared by reaction of beta-enaminones with benzenediazonium tetra fluoro borate substituted especially by fluorine-containing groups (F, CF3, and OCF3). The compounds prepared have been characterized by means of H-1 and C-13 NMR spectroscopy. In the case of reaction of 5-phenylaminohept-4-en-3-one with 2,6-dichloro-4-trifluoromethylbenzenediazonium tetrafluoroborate the product of azo coupling on phenylamino group of the corresponding pyrazole has been isolated and identified. The intermediate (4-(4-methoxyphenyldiazenyl)-5-methylaminohept-4-en-3-one) on the route from enaminone to pyrazole has been isolated.
