English Abstract

3-Trifluoromethyl-5-thienyl-pyrazole (59,60,61) were prepared by re fluxing of trifluoromethyl-l,3-dikentones with hydrazine hydrate in the presence of hydrochloric acid.

On the other hand reaction of N-substituted hydrazine with trifluoromethyl-1,3-diketones give two isomeric products of 1- substituted-3(and5)-trifluoromethyl-5(and3)-theinyl-pyrazoles 62-64 (ai,a2) and 65-67(bi,b2) in different ratios .The structures of above products were assigned on the basis of their nuclear magnetic resonance spectral data (’H-NMR, 13C-NMR), mass spectral data, and elemental analysis.
