Novel Cyclodiphosph(V)azane-thiolate and thiocarbonate Derivatives

The work could be summarized in the followings: 1)All the aromatic amines so far studied react with phosphorus pentachloride to give dimeric products for which the name hexachlorocyclodiphosph(V)- azanes was adopted. 2)In the numerous reactions between hexachlorocyclo- diphosph(V)azanes and some containing sulfur derivatives such as i) 1, 3-dithiol-2-thione-4, 5-dithiolate (dimit)(II). ii) 1,3-trithiocarbonate(III). Following the successful preparation of the cyclodiphosph(V)azane dithiolate(IV) and trithiocarbonate(V), attention was directed to investigate the chemical behavior of such compounds towards different metal salts. The assignments of the proposed structures (IV) ,(V) , (VI) and (VII) were based on the following points: i-The micro analytical data, which are in good agreement with the proposed structures. ii-Spectroscopic studies, which includes IR , ultraviolet spectra, mass spectrometric, electronic spectroscopic studies and magnetic moment measurements iii-The biological activity of the ligands used and their metal complexes were studied. The results concluded the some activity and other reduced this activity with respect to parent ligands
