Synthesis of trifluoromethylated pyrazoles from trifluoromethylenaminones and monosubstituted hydrazines

Cyclocondensation of monosubstituted hydrazines 2a-c with trifluoromethylenaminones 1a-c afforded 3-CF3 and (or) 5-CF3 pyrazoles 3-6. Addition of N-methylhydrazine to enaminone led to 3-CF3 pyrazole as the major product, w
