Trichonnethylphosphonsäuredihydrazid und 3.6-Bi8(trichlormethyl)-3.6-dioxo-1.2.4.5-tetraaza-3.6-diphosphacyclohexan / Trichloromethylphosphonic Acid Dihydrazide and 3,6-Bis(trichloromethyl)-3,6-dioxo-1,2,4,5-tetraaza-3,6-diphosphacyclohexane
Abstract:Abstract The title compounds are prepared from trichloromethylphosphonic acid dichloride and excess hydrazine hydrate, and from the dihydrazide and the dichloride in the presence of triethylamine, resp. They are characterized by elemental analysis, mass spectra, 1H and 31P NMR spectra, IR and Raman data. Thin layer chromatographic experiments show that in the raw material of the ring compound two isomers (probably cis- and trans-) are p… Show more
Das Dihydrazid (II) wird durch Umsetzung des Phosphonsäuredichlorids (I) mit überschüssigem Hydrazinhydrat erhalten und bildet mit äquimolaren Mengen des Dichlorids (I) in Gegenwart von Triethylamin das cyclische Produkt (III).
