AbstractStructural models of silicon imidonitride (SiNH) solids are studied using density functional methods. The porous models have densities between 1.6 and 2.4 g/cm3 with pore sizes between 4.5 Å and 7.5 Å. The networks consist of Si-N and N-H bonds only, with N-H and N-H2 groups located at the internal surface. Calculated Raman spectra compare very well with experimental results. We observed proton transfer reactions from an inserted malononitrile molecule to the SiNH-host during Car-Parrinello molecular dynamic simulations. The proton affinity of porous silicon imidonitride structures is confirmed by an energy gain for the proton transfer reaction to both N-H and N-H2 groups.

The carbon acid 1-(4-nitrophenyl)-1-nitroethane reacts with phenyltetramethylguanidine in the aprotic solvents acetonitrile, benzonitrile, and chlorobenzene in a bimolecular proton transfer reaction. The primary isotope effects, kH/kD, for these reactions at 25 °C are 8.5 ± 0.4, 6.1 ± 0.4, and 16 in acetonitrile, benzonitrile, and chlorobenzene respectively. The magnitude of the isotope effects on the enthalpy of activation [Formula: see text] are 2.3 ± 0.2, 1.6 ± 0.7, and 4.2 ± 0.6 kcal mol−1, which indicates a contribution from proton tunnelling to the reaction rate of the normal substrate.
