The mass spectra of diphenylphosphino- and diarylphosphorohydrazides have been examined.Diphenylphosphinohydrazide (Ia) behaves in a manner comparable to derivatives having the diphenylphosphinyl moiety (Ib-e).The molecular ion of diarylphosphorohydrazide

1,3-Dicarbonyl compounds (III) reacted with the phosphorus hydrazides 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
