PHOSPHORUS SULFUR AND SILICON AND THE RELATED ELEMENTS
2-Arylhydrazono-2-bromo-1-[3-ethoxycarbonyl-5-methyl-1-p-tolyl]pyrazo]-4-yl
ethanone (5a-e) were synthesized via reaction of [3-(ethoxycarbonyl-5-methy
l-1-p-tolypyrazol-4-oyl]-2-oxoethyl(dimethyl)sulfonium bromide with N-nitro
soacetarylamides in ethanol. The reactions of hydrazonoyl bromides with eac
h of potassium thiocyanate, thiourea, and alkyl carbodithioates are discuss
ed. Structures of the newly synthesized compounds were elucidated on the ba
ses of spectral data, elemental analyses, and alternative method whenever p
ossible.
