    Description / Table of Contents: Synthesis and NMR Spectra of Diazadiphosphetidines, II1,3,2λ5,4λ5-Diazadiphosphetidines are synthesized from PCl5 and aniline derivatives. They are partially or fully dissociated in solution to give substituted (phenylimido)phosphoric trichlorides. The dependence of the dissociation on the solvent, the temperature, and the concentration has been investigated. The reaction products of anilines and C6H5PCl4 or (C6H5)2PCl3 are exclusively monomers, i. e. they are substituted phenyl(phenylimido)phosphonic dichlorides 3 or diphenyl-(phenylimido)phosphinic chlorides 4, respectively.
    Notes: 1,3,2λ5,4λ5-Diazadiphosphetidine 1 werden aus PCl5 und Anilinderivaten synthetisiert. Sie liegen in Lösung teilweise oder ganz dissoziiert als substituierte (Phenylimido)phosphorsäuretrichloride 2 vor. Es wurde die Abhängigkeit der Dissoziation vom Lösungsmittel, der Temperatur und der Konzentration untersucht. Die Reaktionsprodukte aus Anilinen und C6H5PCl4 oder (C6H5)2PCl3 sind ausschließlich monomer, d. h. es handelt sich um substituierte Phenyl(phenylimido)phosphonsäuredichloride 3 bzw. Diphenyl(phenylimido)phosphinsäurechloride 4.
