In the title indole derivative, C17H15NO4S, the fused dioxolo-indole system is essentially planar [r.m.s. deviation of the 12 fitted atoms = 0.0249 angstrom] and is effectively perpendicular to the appended 4-tolyl ring, forming a dihedral angle of 89.95 (6)degrees. Overall, the molecule has the shape of the letter L. In the crystal, supramolecular layers in the ab plane are formed via weak 4-tolyl-C-H center dot center dot center dot pi(C-6-ring of indole) and S-O center dot center dot center dot pi (1,3-dioxole) contacts. The aforementioned interactions along with interatomic H center dot center dot center dot H and H center dot center dot center dot O contacts are all shown to make significant contributions to the calculated Hirshfeld surfaces.

Orobanche and Phelipanche species (the broomrapes) are root parasitic plants, some of which represent serious weed problems causing heavy yield losses on important crops. Current control relies on the use of certain agronomic practices, resistant crop varieties, and herbicides, albeit success has been marginal. Agronomic practices such as the use of allelopathic species in intercropping or cover crops, or the use of direct seedling over residues of allelopathic species incorporate the principle of allelopathy exerted by molecules exuded from roots or released by crop residues to control broomrapes. In addition, the isolation of natural substances from root exudates of plants with potential to inhibit broomrape development opens the door to the design of new herbicides based on natural and benign sources. Ryecyanatines A and B and ryecarbonitrilines A and B, the first new substituted cyanatophenol, substituted cyanatobenzo[1,3]dioxole, and the latter two new substituted benzo[1,3]dioxolecarbonitriles were isolated from rye (Secale cereale L.) root exudates. They were characterized as 4-cyanato-2-methoxyphenol, 2-cyanato-benzo[1,3]dioxole, 2-methoxybenzo[1,3]dioxole-5-carbonitrile and benzo[1,3]dioxole-2-carbonitrile by spectroscopic (essentially NMR and HRESI MS spectra) methods. These compounds were investigated for allelopathic activity on Orobanche germination and development. Ryecarbonitriline A induced germination of Orobanche cumana seeds, and this germination can be considered as suicidal because O. cumana does not parasite rye roots and cannot survive without host resources beyond germination stage. In addition, ryecyanatine A promotes a rapid cessation of O. cumana, Orobanche crenata and Orobanche minor radicle growth with the promotion of a layer of papillae at the radicle tip in O. cumana and O. crenata hampering the contact of the parasite to the host. Ryecarbonitriline B also displayed the same activity although being less active than ryecyanatine A and mainly restricted to O. cumana. (C) 2014 Elsevier Ltd. All rights reserved.

Thioxoethanal S-oxide, as well as its mono and dimethyl derivatives, have been generated, under flash vacuum thermolysis conditions, using the retro-Diels-Alder cleavage of the corresponding 2,3-dihydro-1,4-oxathiin S-oxides. The parent compound, thioxoethanal S-oxide, was characterized by low temperature IR, and in particular photoelectron spectroscopy. The experimental IP’s, as well as the MNDO calculations, are in agreement with the proposed structure [the (E)-s-cis conformation being the most stable], and exclude the formation of the cyclic isomers beta-sulfine and 3-thia-1,2-dioxole. The methyl derivatives were characterised by low temperature IR and NMR spectroscopy, and chemical trapping by 2,3-dimethyl-1,3-butadiene.

Now introduce a scientific discovery about this category.

Pervaporation of binary mixtures (CH2Cl2-CHCl3, CHCl3-CCl4 CH2Cl2-CCl4) through two amorphous copolymers of 2,2-bis-trifluoromethyl-4,5-difluoro-1,3-dioxole and tetrafluoroethylene was studied at different temperatures, feed composition, and downstream pressure. It was shown that the copolymer with the larger content of the dioxole comonomer and having the greater free volume (AF 2400) is more permeable, whereas selectivity of separation of the two copolymers are similar for some regimes. The dependence of permeation rate and selectivity on the process parameters of the AF copolymers indicated that mobility selectivity prevails for pervaporation of the mixtures studied through these membrane materials. The deviation coefficients used for analysis of mixed permeation indicated strong interactions of the components in pervaporation of binary mixtures. Pervaporation separation index (PSI), which depends on permeability and selectivity of pervaporation, was used to characterize the performance of the process. It was shown that PSI increases for higher contents of the components enriched in the permeate and at higher temperatures. (C) 2004 Elsevier B.V. All rights reserved.

The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic, and theoretical assessments of solvent structures and their interactions with reaction intermediates and transition states. 43157-50-2, Name is 2-Thioadenosine, SMILES is S=C1NC2=C(N=CN2[C@@H]3O[C@H](CO)[C@@H](O)[C@H]3O)C(N)=N1, in an article , author is Takahashi, S., once mentioned of 43157-50-2, Electric Literature of 43157-50-2.

Nanocomposite membranes based on nano-sized SiO2 particles with chemical coupling to the polymer matrix are described with special emphasis on gas permeation properties. In this paper, poly(ether imide) with reactive imide rings in the backbone was used as the matrix to which the SiO2 particles were chemically bonded via an amine-containing silane coupling agent. Four types of nanocomposite membranes were prepared by solution casting and melt processing and characterized in terms of morphology and void volume formed due to adding SiO2 particles. The relative gas permeability of the nanocomposite with chemical coupling to matrix was decreased by the presence of SiO2 particles. Diffusion coefficients computed from time lag data also decreased with SiO2 content. However, solubility coefficients computed by dividing the experimental permeability by the diffusivity obtained from the observed time lag increased with SiO2 content contrary to simple composite theory. These permeation properties are discussed in terms of the void volume fraction estimated by density observations. In addition, TEM and SEM were used to explore the morphology of these nanocomposite membranes. (c) 2006 Elsevier Ltd. All rights reserved.

In a document, author is Considine, RF, introduce the new discover, Reference of 29836-26-8.

An atomic force microscope has been employed to measure the force of interaction between a micron-sized colloidal sphere and a flat plate, both coated with a copolymer of perfluoro(2,2-dimethyl-1,3-dioxole) and tetrafluoroethylene (Teflon AF1600) in water, glycerol, formamide, ethylene glycol, ethylammonium nitrate, formic acid, ethanol, methanol, diiodomethane, 1-bromonaphthalene, hexadecane, and hexane. A long-range force of attraction was measured in water and, with the exception of the n-alkanols and n-alkanes, all the organic liquids. The results indicate that there is a macroscopic long-range attraction between solvophobic surfaces that has a different origin from that of the hydrophobic interaction observed at the molecular level, The results also indicate that there is a solvophobic force that is not due to either orientational ordering propagated by hydrogen bonds, electrostatic (or polarization) effects, or condensates of loosely attached surface material; all mechanisms that have been invoked previously to explain the macroscopic hydrophobic force. The force curves measured in the organic liquids provide a new perspective which is consistent with the hypothesis that submicroscopic air bubbles adhering to the macroscopic surfaces are responsible for a long-range attraction.
