AM1 study of photoelectronic spectra .8. Direct calculations of ionization in the study of conformations of some methoxy-substituted benzenes

Ionization energies of four model compounds with known conformations, i.e., benzo-1,3-dioxole, 2-methoxyphenol, benzo-1,3-dioxole-5-carbaldehyde (piperonal), and 4-hydroxy-3-methoxybenzaldehyde, have been calculated by the ab initio AM1 method, using the formalized scheme of configuration interactions. It has been demonstrated that this method is adequate for the study of photoelectronic spectra of methoxy(hydroxy)-substituted benzenes. The ionization energies of 1,2-dimethoxybenzene, 3,4-dimethoxybenzaldehyde, and 4-hydroxy-3,5-dimethoxybenzaldehyde have been calculated for various orientations of the o-methoxy(hydroxy) groups. It has been revealed that three first ionization potentials corresponding to the states with vacancies on the pi-MO depend on the torsion angle. It has been established by comparison of calculated and experimental ionization potentials that in gas the compounds with adjacent methoxy groups have one O-Me bond parallel with the plane of the benzene ring, while another group is nearly perpendicular to this plane. Conformations of the heavy-atom framework are planar for gaseous molecules with adjacent methoxy and hydroxy groups.

Enhancement of diffusion in a high-permeability polymer by the addition of nanoparticles

A nanocomposite was formed by adding fumed silica to the high-permeability random copolymer of tetrafluoroethylene (TFE) and 2,2-bis(trifluoromethyl)-4,5-difluoro-1,3-dioxole (PDD). The self-diffusion constant of pentane in cast films of the pure polymer and nanocomposites containing 10, 20, 25, and 30 wt % fumed silica was measured. The addition of 30 wt % fumed silica increased the self-diffusion constant by an order of magnitude. For the pure polymer and all four nanocomposite compositions, the apparent self-diffusion constants are a function of the time over which diffusion is observed, Delta, in the pulse field gradient experiment. At a given level of fumed silica, diffusion appears to be faster when observed over shorter times and decreases toward a plateau value at long times. This result is qualitatively indicative of tortuous diffusion. The addition of fumed silica not only increases the apparent self-diffusion constants but also changes the dependence of the apparent self-diffusion constants on Delta. The self-diffusion constants decrease more slowly as a function of Delta, indicating better connectivity of the more permeable domains. The apparent diffusion constants also increase as a function of time after the introduction of pentane. This phenomenon is observed in the pure polymer as well and is described as conditioning of the membrane. Conditioning of the membrane increases diffusion constants initially; but after a few months, aging of the membrane leads to a decrease in translational mobility.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 122111-11-9, you can contact me at any time and look forward to more communication. COA of Formula: C20H18F2O8S.

Crystal structure of 5-(1,3-dithian-2-yl)-2H-1,3-benzodioxole

In the title compound, C11H12O2S2, two independent but virtually superimposable molecules, A and B, comprise the asymmetric unit. In each molecule, the 1,3-dithiane ring has a chair conformation with the 1,4-disposed C atoms being above and below the plane through the remaining four atoms. The substituted benzene ring occupies an equatorial position in each case and forms dihedral angles of 85.62 (9) (molecule A) and 85.69 (8)degrees (molecule B) with the least-squares plane through the 1,3-dithiane ring. The difference between the molecules rests in the conformation of the five-membered 1,3-dioxole ring which is an envelope in molecule A (the methylene C atom is the flap) and almost planar in molecule B (r.m.s. deviation = 0.046 angstrom). In the crystal, molecules of A self-associate into supramolecular zigzag chains (generated by glide symmetry along the c axis) via methylene C-H center dot center dot center dot pi interactions. Molecules of B form similar chains. The chains pack with no specific directional intermolecular interactions between them.

PHOTOCHEMICAL-REACTIONS .153. PHOTOCHEMISTRY OF ACYLSILANES – PHOTOLYSES AND THERMOLYSES OF ALPHA,BETA-EPOXY SILYL KETONES

The photolyses and thermolyses of the alpha,beta-epoxy silyl ketones 5 and 6 are described. On n,pi*-excitation, the silyl ketones 5 and 6 were transformed to the ketone 7 and the ketene 8 in quantitative yield. The formation of 8 may be explained by initial cleavage of the C(alpha)-O bond and subsequent C(1) –> C(2) migration of the (t-Bu)Me2Si group. In contrast to the acylsilanes 5 and 6. the photolyses of the analogous methyl ketones 11 and 12 gave a very complex mixture of products. On thermolysis, 5 and 6 yielded the ketone 7 and the acetylenic compound 9, which were probably formed via a siloxycarbene intermediate. In addition, the 1,3-dioxole 10 was formed via an initial C(alpha)-C(beta) bond cleavage leading to the ylide g and subsequent intramolecular addition of the carbonyl group. The analogous 1,3-dioxole 13 was obtained on pyrolysis of the methyl ketones 11 and 12.
