Isomerization of α-Pinene Oxide in Dimethyl Sulfoxide

DFT study of dimers of dimethyl sulfoxide in gas phase

Density functional (DFT) calculations at M05-2x/aug-cc-pVDZ level were used to analyze the interactions between dimethyl sulfoxide (DMSO) dimers. The structures obtained have been analyzed with the Atoms in Molecules (AIMs) and Natural Bond Orbital (NBO) methodologies. Four minima were located on the potential energy surface of the dimers. Three types of interactions are observed, CH•••O, CH•••...

Clinical Considerations of Dimethyl Sulfoxide

Unanticipated Stickiness of α-Pinene.

The adsorption of α-pinene to solid surfaces is an important primary step during the chemical conversion of this common terpene over mesoporous materials, as well as during the formation of atmospheric aerosols. We provide evidence of tight and loose physisorbed states of α-pinene bound on amorphous SiO2 as determined by their adsorption entropy, enthalpy, and binding free energies characterize...

Biological activities of α-pinene and β-pinene enantiomers.

The antimicrobial activities of the isomers and enantiomers of pinene were evaluated against bacterial and fungal cells. The agar diffusion test showed that only the positive enantiomers of the α- and β-isomers of pinene were active. The minimal inhibitory concentration (MIC) and minimal microbicidal concentration (MMC) of these monoterpenes were also determined, confirming that the positive en...

Diaqua­bis­(dimethyl sulfoxide-κO)­disaccharinatocadmium

The title compound, [Cd(C(7)H(4)NO(3)S)(2)(C(2)H(6)OS)(2)(H(2)O)(2)], contains a Cd(2+) cation in an octahedral coordination environment. The metal atom is surrounded by the two different neutral ligands dimethyl sulfoxide (DMSO) and water, each coordin-ating through the O atom. The anionic saccharinate (sac; 1,1,3-trioxo-2,3-dihydro-1λ(6),2-benzothia-zol-2-ide) ligand coordin-ates through the ...
