| Abstract: | The substitution reaction of bis(anilino)phosphine oxide (C 6 H 5 NH) 2 P(O)H (1) with trans-PtCl 2 (SEt 2 ) 2 yields the novel unprecedented phosph(V)azane-platinum complex cis-Pt(SEt 2 ) 2 ClHNPhP(O)NPh(HNEt 3 )] (3). In this reaction, the bis(anilino)phosphine oxide undergoes P–H activation and a Pt(II)–P(V) bond instead of Pt–N bond forms. 31 P NMR spectra readily distinguish between the “N” and “P” bonding modes. The reaction requires the presence of triethylamine (TEA) as a base in order to deprotonate the phosphazane ligand and is separated as Et 3 NH+Cl?, whereas HTEA+ exists in the final product 3 and is acting as charge balancing and H-bond structure directing agent. The products have been fully characterized by means of IR; MS; UV-Vis; and 1 H, 13 C, and 31 P NMR spectroscopy. |
