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 dithioacet-als and sequent alkylation. These compounds were characterized by ~1H NMR, ~(13)C NMR spectra and ele-mental analyses, and part of them were further characterized by IR and MS techniques.
