The exact solution of the one-dimensional Schrodinger equation with symmetric trigonometric double-well potential (DWP) is obtained via angular oblate spheroidal function. The results of stringent analytic calculation for the ground state splitting of ring-puckering vibration in the 1,3-dioxole (as an example of the case when the ground state tunneling doublet is well below the potential barrier top) and 2,3-dihydrofuran (as an example of the case when the ground state tunneling doublet is close to the potential barrier top) are compared with several variants of approximate semiclassical (WKB) ones. This enables us to verify the accuracy of various WKB formulas suggested in the literature: 1. ordinary WKB, i.e., the formula from the Landau and Lifshitz textbook; 2. Garg’s formula; 3. instanton approach. We show that for the former case all three variants of WKB provide good accuracy while for the latter one they are very inaccurate. The results obtained provide a new theoretical tool for describing relevant experimental data on IR spectroscopy of ring-puckering vibrations.

Additions of inert tetrabutylammonium hexafluorophosphate (Bu4NPF6) to a solution of TMDO/DDQ in dichloromethane (where TMDO = 2,2,6,6-tetramethylbenzo[1,2-d, 4,5-d]bis[1,3]-dioxole, donor, and DDQ = dichlorodiyano-p-benzoquinone acceptor) is accompanied by drastic changes in the electronic spectrum which are related to the appearance of the DDQ and TMDO+ ion radicals and a decrease in the concentration of the neutral molecules and the charge transfer complex [TMDO,DDQ]. These changes point to a considerable rise (of about three orders of magnitude) in the apparent electron transfer equilibrium constant (K-ET) for this donor/acceptor pair upon increasing the electrolyte concentration from 0 to 0.5 M. Accordingly, the ion-radical fractions and K-ET values are higher in dichloromethane, at high electrolyte concentrations, than in acetonitrile (where the effect of Bu4NPF6 is less pronounced). Similar trends of the apparent equilibrium constants are observed for the tetramethyl-p-phenylenediamine/tetracynaoethylene pair. Electron-transfer equilibrium constants for both donor/acceptor dyads obtained from spectral measurements are related to those derived from the redox potentials of the reactants. The effects of media variations on the electron-transfer equilibria are discussed within the ion-pairing and ionic-activity frameworks.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 604-69-3, in my other articles.

In the title compound, C23H15N3O2, significant deviations from planarity are evidenced in the values of the dihedral angles formed between the amino-benzene ring and the benzene rings of the 1,3-benzodioxole [65.38 (12)degrees] and 1,2dihydronaphthalene [26.27 (14)v] residues; the dioxole ring has an envelope conformation with the methylene-C being the flap atom. The amino-H atoms form hydrogen bonds to one of the dioxole-O atoms and to one of the cyano-N atoms to generate a two-dimensional array with a zigzag topology that stacks along the ((1) over bar 0 2) plane.

Molecular modeling techniques are applied to study the cavity size distributions and transport properties of two very permeable polymers, poly (1-trimethylsilyl-1-propyne) (PTMSP) and a random copolymer of tetrafluoroethylene and 2,2-bis(trifluoromethyl)-4,5-difluoro-1,3-dioxole (TFE/BDD), which have very similar and large fractional free volumes, but very different permeabilities. Using atomistic models, cavity size (free volume) distributions determined by a combination of molecular dynamics and Monte Carlo methods are consistent with the observation that PTMSP is more permeable than TFE/BDD. The average spherical cavity size in PTMSP is 11.2 angstrom, whereas it is only 8.2 angstrom in TFE/BDD. These cavity size distributions determined by simulation are also consistent with free volume distributions determined by positron annihilation lifetime spectroscopy (PALS). The diffusivity, solubility and permeability Of CO2 in these polymers were also obtained through molecular simulation. The diffusivity and permeability Of CO2 in PTMSP are higher than in TFE/BDD. Good agreement is observed between the simulation and experimental data.

Eighteen racemic beta-aryl-gamma-lactones derived from simple aromatic aldehydes have been obtained in the chemical synthesis. Iodolactones (5c and 6c) were synthesized from (E)-4-(benzo[d][1′,3′]-dioxol-5′-yl)-but-3-en-2-one (1). Reductive dehalogenation of iodolactones 5a-c and 6a-c afforded gamma-ethyl-gamma-lactones (7a-c, 8a-c) whereas the unsaturated lactones (9a-c, 10a-c) were obtained by dehydrohalogenation of iodolactones. All synthesized lactones were fully characterized by spectroscopic data (NMR, IR, HRMS) and subjected to the tests on the antifeedant activity towards Tribolium confusum, Trogoderma granarium and Sitophilus granaries as well to the tests on the antifungal activity towards four Fusarium species. The biological tests allowed to find some relationships between the structure and biological activity of the compounds studied. gamma-Ethyl- gamma-lactones 7a-c, 8a-c and unsaturated lactones 9a-c, 10a-c were usually stronger antifeedants than their parent iodolactones 5a-c and 6a-c. trans-Iodolactones 6a-c were more active than cis isomers 5a-c both in antifeedant and antifungal assays. The structure of aromatic substituent was the key factor in antifungal activity. The lactones with benzo [d][1,3]dioxole ring (5c, 6c, 7c, 8c, 9c) were the most active whereas those with unsubstituted benzene ring exhibited almost no activity.

The reaction of maleimide with Rh(II)-ketocarbenoids, derived from acyclic diazocarbonyl compounds, proceeds chemoselectively at the oxygen atom of the imidic C=O group to give carbonyl ylides as reactive inter-mediates. The carbonyl ylide generated from maleimide and ethyl diazoacetate reacts intermolecularly with the double bond of another molecule of maleimide to yield tricyclic spiroadducts via [3+2]-cycloaddition. Intramolecular stabilization is characteristic for carbonyl ylides with two bulky electron-withdrawing groups at the carbanionic center and occurs in two different ways, depending on the structure of the substituents: carbonyl ylides from diazomalonate, which possess two alkoxycarbonyl groups at the carbanionic C-atom, experience a 1,3-dipolar electrocyclization with formation of an oxirane, while carbonyl ylides with at least one a-acyl group, derived from diazoacetoacetate or diazoacetylacetone, undergo an intramolecular 1,5-dipolar electrocyclization to produce 1,3-dioxole derivatives of maleimide.

Phytohemical investigation of the EtOAc extract of leaves and stems of Bulbophyllum kwangtungense Schlecht., belonging to the orchid family was carried out. Two new stilbenods were isolated by repeat column chromatography and characterized: one is bibenzyl compound, 5-(2, 3-dimethoxyphenethyl)-6-methylbenzo [d] [1, 3] dioxole (1), and the other dibenz [b, f] oxepine, 10, 11-dihydro-2, 7-dimethoxy-3, 4-methylenedioxy dibenzo b, f] oxepine (2). Their structures were established on the basis of analyses of spectroscopic evidence, particularly by two-dimensional NMR spectroscopic analysis. Bibenzyl compound with a methyl group in the benzene ring is rarely found from natural sources. Natural oxepines are very rare, and most of them were reported to have good anti-tumor activities. In addition, anti-tumor activities of the new compounds were also evaluated. Among the compounds isolated, compound 2 showed anti-tumor activities with IC50 value of 47.2 mu g/mL in vitro against cultures of Hela cells.

Methacrolein is a major product of isoprene ozonolysis, and methacrolein oxide is an important ozonolysis intermediate. We use CBS-QB3 and RRKM/master equation calculations to characterize all methacrolein formation pathways and all the unimolecular reactions of methacrolein oxide. Our predicted methacrolein yield agrees with experiment if we assume that all of the dioxirane formed from methacrolein oxide decomposes to methacrolein. The vinyl group of methacrolein oxide allows the species to cyclize to a dioxole with a reaction barrier lower than the barriers to either hydroperoxide or dioxirane formation. Two dioxole derivatives, 1,2-epoxy-2-methyl-3propanal and 2-methyl-3-oxopropanal, should be measurable products of isoprene ozonolysis. (C) 2007 Elsevier B.V. All rights reserved.

We have used a novel microwave-assisted method developed in our laboratories to synthesize a series of ruthenium-thiosemicarbazone complexes. The new thiosemicarbazone ligands are derived from benzo[d][1,3]dioxole-5-carbaldehyde (piperonal) and the complexes are formulated as [(diimine)(2) Ru(TSC)](PF6)(2) (where the TSC is the bidentate thiosemicarbazone ligand). The diimine in the complexes is either 2,2′-bipyridine or 1,10-phenanthroline. The complexes have been characterized by spectroscopic means (NMR, IR and UV-Vis) as well as by elemental analysis. We have studied the biophysical characteristics of the complexes by investigating their anti-oxidant ability as well as their ability to disrupt the function of the human topoisomerase ll enzyme. The complexes are moderately strong binders of DNA with binding constants of 10(4) M-1. They are also strong binders of human serum albumin having binding constants on the order of 10(4) M-1. The complexes show good in vitro anticancer activity against human colon cancer cells, Caco-2 and HCT-116 and indeed show some cytotoxic selectivity for cancer cells. The IC50 values range from 7 to 159 mu M (after 72 h drug incubation). They also have antibacterial activity against Gram-positive strains of pathogenic bacteria with IC50 values as low as 10 mu M: little activity was seen against Gram-negative strains. It has been established that all the compounds are catalytic inhibitors of human topoisomerase II. (C) 2011 Elsevier B.V. All rights reserved.
