In the molecule of title compound, C12H14O3, the benzodioxole ring system is essentially planar. In the crystal structure, weak intermolecular C-H center dot center dot center dot O hydrogen bonds link molecules into chains along the c axis, and pi-pi contacts between dioxole rings and between dioxole and benzene rings of the benzodioxole ring systems [centroid-centroid distances 3.702 (3) and 3.903 (3) angstrom] may further stabilize the structure. Two C-H center dot center dot center dot pi interactions are also found.

Analytic calculation of ground state splitting in symmetric double well potential

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.

Spirocyclic and fused derivatives of maleimide based on intra- and intermolecular reactions of carbonyl ylides from diazocarbonyl compounds

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.

Synthesis and cytotoxicity studies of new dimethylamino-functionalised and aryl-substituted titanocene anti-cancer agents

From the carbolithiation of 6-N,N-dimethylamino fulvene (3a) and different lithiated aryl species [p-N,N-dimethylanilinyl lithium, p-anisyl lithium and 4-lithio-benzo[1.3]dioxole (2a-c)], the corresponding lithium cyclopentadienide intermediates 4a-c were formed. These three lithiated intermediates underwent a transmetallation reaction with TiCl4 resulting in dimethylamino-functionalised and aryl-substituted titanocenes 5a-c. When these titanocenes were tested against LLC-PK cells, the IC50 values obtained were of 54, 45 and 26 mu M for titanocenes 5a, b and c, respectively. The most cytotoxic titanocene in this paper, 5c is approximately 10 times less cytotoxic than cis-platin, which showed an IC50 value of 3.3 mu M, when tested on the LLC-PK cell line, but approximately 100 times better than titanocene dichloride.

Synthetic strategies towards the carbenoid reactions of alpha,beta-acetylenic carbonyls

Catalytic reactions of alpha, beta-conjugated carbonyl compounds have been a practical tool towards the synthesis of different useful heterocyclic compounds. Despite the numerous reactions with carbon-carbon double bond conjugated carbonyls, reactions of acetylenic carbonyls are limited. In this study, efficient dioxole synthesis was carried out via acetylenic aldehydes and butadiene formation was preferred over cyclopropene formation via acetylenic esters as different functional groups on these substrates change the product distribution. Both reaction conditions (such as solvent and temperature) and electrophilic structure of metal carbenoids alter the product distribution; acceptor (A), donor-acceptor (DA), and acceptor-acceptor (AA) functionalized diazo compounds yield different product types over different mechanisms.

Degradation mechanism and materials for 157 nm pellicles

A great deal of resources has been invested by the semiconductor industry as a whole to make ready 157 nm as the next lithography technology node. Despite of all this effort serious infrastructure issues remain to be solved. Perhaps the first one is the availability of CaF2, but a close second is a suitable soft-pellicle material. It has been previously reported(1-4) that standard 193 nm materials, like Teflon AF(R) and Cytop(R), fail catastrophically upon exposure at 157 nm radiation; and that their transmission is very poor to non-existent. In this paper we report data showing that these materials have higher transmission and lifetimes than previously thought 2. The physical lifetime of Cytop(R) of nearly 500 J/cm(2) is remarkably high, although the transmission varies as a function dose suggesting physical and chemical changes from the onset. For Teflon AF(R) the transmission is a more complex function of exposure dose, suggesting competing mechanisms. From experiments run with PVDF (polyvinyl difluoride), we conclude that the widely reported photodarkening effect is due to the presence of hydrogen in close proximity to a fluorine atom. From IR spectra we conclude that the dioxole moeity in Teflon AF(R) undergoes a series of photochemical reactions that lead to the physical destruction of the polymer.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 604-69-3, you can contact me at any time and look forward to more communication. Recommanded Product: beta-D-Glucose pentaacetate.

Chiral centers C2, C3 and C4 in D-(-)-arabinose are fixed in the densely oxygenated cyclopentane ring at the 1,3-dioxole ring fusion and at the C atom bearing the siloxy functionality. The molecules are involved in two kinds of hydrogen bonding: an intramolecular hydrogen bond exists between O6 and O8-H8′ [O8-H8’…O6; O8-H8′ = 0.76 (4), H8’…O6 = 2.04 (4), O8…O6 = 2.768 (4) angstrom and O8-H8’…O6 = 161 (5)-degrees]; H6′ bonds together two molecules related by a 2(1) screw axis along the a axis [O6-H6’…O8 (x – 0.5, – y + 1.5, – z); O6-H6′ = 0.84 (5), H6’…O8 = 2.08 (5), O6…O8 = 2.917 (4) angstrom and O6-H6’…O8 = 175 (4)-degrees].

Synthesis and polymerization of novel perfluorodioxolane based monomers

Perfluorodioxolane monomers that have an unprecedent rpolymerization site were synthesized by utilizing a direct fluorination reaction. Particularly, some of them successfully polymerized with tetrafluoroethylene to afford copolymers. Although reactivity of the monomers was similarly lower than that of the well-known perfluorodioxole based monomer; 2,2-bis(trifluoromethyl)-4,5- difluoro-1,3-dioxole, the obtained polymers may be addressed to advanced materials because of their superior thermal properties.
