, p. 396 - 399 (2007/10/02)
1,3-Dicarbonyl compounds (III) reacted with the phosphorus hydrazines to give the corresponding hydrazones.When the hydrazones of ethylacetoacetate were heated at their melting points, they were converted to the corresponding pyrazolin-5-ones.The spectral characteristics of these pyrazolinones were studied.
