  1. Structure and reactivity of cyclic imido derivatives of phosphoric acid

    … showed evidence of cleavage of both imide P-N bonds. This indicates that the ring opening in these derivatives is much slower than the second P-N cleavage in the ring-opened intermediate (30, scheme 11). On the other hand, methanolysis of …

  2. Tertiary N-acyl phosphoramidates : a mechanistic study of their formation and collapse in reactions with nucleophiles

    … studied, and the possible mechanisms of the P-N bond cleavage, followed by the N-methyl transfer from the phosphoryl to the carbonyl centre are discussed.

  3. Vibrational characterisation of coordination and biologically active compounds by means of IR absorption, Raman and surface-enhanced Raman spectroscopy in combination with theoretical simulations

    … influence of the metal coordination on the P–N bond length. In the next section the vibrational spectra of four hexacoordinated silicon(IV) and germanium(IV) complexes with three symmetrical bidentate oxalato(2-) ligands have been elucidated. Kinetic investigations of the hydrolysis of two of …

  4. Quantum chemical modeling of redox reactivity, degradation pathways and persistence for aqueous phase contaminants

    … at similar reaction rates. Hydrolysis of the P-N bond in HMPA is the only thermodynamically favorable reaction that may lead to its degradation under strongly reducing conditions. Through calculation of aqueous Gibbs free energies of activation for all potential reaction mechanisms, it is …

    … = η5-cyclopentadienyl, iPr = isopropyl), toward bond activation, cycloaddition and nucleophilic addition has been examined. The complex [CpFe(CO)2{PNiPr2}]+ reacts with primary, secondary, and tertiary silanes to form the silyl phosphine complexes [CpFe(CO)2{P(H)(SiR3)NiPr2}]+ (SiR3 = SiPhH2, …
