Theoretical and experimental investigation of reactions between dialkyl phosphites and tert-butylphosphaethyne-butylphosphaethyne revealed that the preferred reaction route resulted in formation of a phosphaalkene containing a fragment C

Numerical solving of problem of diffusion of low-molecular solvent in polymer materials with the moving interface

On projective motions of five-dimensional spaces of special form pseudo-Riemannian manifolds (M, g) admitting projective motions (h-spaces). A similar problem for n

Magnetic anisotropy of cyclopropane and epoxide rings

Projective symmetries and laws of conservation in the K-spaces determined by gravitational fields

The nature of "anomalous" chemical shifts in certain heterocycles based on nonempirical calculations and localization analyzed. A nonempirical calculation has been made of the electronic structure of a number of six

Rearrangements and proton transfer in nitrones by quantum chemistry and molecular dynamics oxaziridine, is via the structure C(O)H2-NH and then directly to the amide product. © 2002 Elsevier Science B.V

Diagrams of isoshielding lines of C-N bonds and nitrogen and phosphorus lone pairs, as well as a C-N bond, have been calculated. The magnetic shielding constants of the protons were

Contributions of localized MO's to the magnetic shielding constants of protons in YPX3 molecules molecules have been carried out. 2. The decisive contribution to the shielding of a proton is made by the C
