| Abstract: | Methods are proposed for the synthesis of phosphorylated pyrazolones by condensation of phosphonates of  -keto(formyl) esters with hydrazine and its derivatives. The IR spectra are presented, and the fine structures of the compounds are discussed.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 4, pp. 513–516, April, 1977. |
