The first oligomeric phosphazene in which each phosphorus center features a PH functionality (3) was obtained from the amidophosphane 1 or its zirconium complex 2.

Reactions of aminobis(diorganylamino)phosphanes (R2N)2PNH2 (R = iPr (a), Cy (b)) with Cp2MCl2 (M = Ti, Zr, Hf), CpTiCl3, and TiCl4 lead to the formation of the transition-metal complexes (R2N)2PN(H)MCp2Cl (M = Ti (1b), Zr (2a,b), Hf (3a,b)) (R2N)2P(H)NTiCpCl2 (8a,b), and (R2N)2P(H)NTiCl3 (10a,b), respectively. The influence of electronic effects of the metal fragment on the resulting equilibrium between the (NH)-phosphanylamido and the tautomeric (PH)-iminophosphorane form is presented in detail. Computational studies unambiguously confirm the experimental results. The molecular structures of 2a, 3a, and 8b have been determined by single-crystal X-ray diffraction.
