A series of dipyrazolylmethanones were synthesized via the hydrazinolysis of ethyl 5-amino-3- methylthio-1H-pyrazole-4-carboxylate (1), followed by the condensation with substituted ketene dithioacetals and sequent alkylation. These compounds were characterized by 1H NMR, 13C NMR spectra and elemental analyses, and part of them were further characterized by IR and MS techniques.

Key words: pyrazole, dipyrazolylmethanone, ketene dithioacetal, synthesis
