Benzo[d][1,3]dioxole gathered pyrazole derivatives (4a-i) were synthesized by the reaction of chalcones with phenyl hydrazine in presence of absolute alcohol as a solvent. Chalcones were prepared by the Claisen-Schmidt reaction between 1-(benzo[d][1,3]dioxol-5-yl)ethanone (2) and substituted aromatic aldehydes. The synthesized compounds were characterized by spectral and elemental analysis data. Furthermore, Benzo[d][1,3]dioxole gathered pyrazole derivatives (4a-i) were evaluated for their in vitro antimicrobial activity. Among the newly synthesized compounds 4a, 4c, 4 g and 4 h showed the excellent antifungal activity and as well as 4a and 4d showed the excellent antibacterial activity when compared to other compounds.

New research progress on 67217-55-4 in 2021. Chemical research careers are more diverse than they might first appear, as there are many different reasons to conduct research and many possible environments. In an article, author is Blakey, Idriss, once mentioned the application of 67217-55-4, Category: dioxoles, Name is Mono-(6-p-toluenesulfonyl)-β-cyclodextrin, molecular formula is C49H76O37S, molecular weight is 1289.1706, MDL number is MFCD05864975, category is dioxole. Now introduce a scientific discovery about this category.

The photodegradation at 157 nm of thin films of a series of Teflon AF copolymers has been comprehensively examined using electron spin resonance, NMR, FTIR, and Raman spectroscopies, mass spectrometry and X-ray photoelectron spectroscopy. The mechanism of degradation involves reaction at the dioxole units, and as a consequence the sensitivity to degradation increases across the series Teflon AF 1200, 1600, and 2400. A major volatile product is hexafluoroacetone formed by degradation at the dioxole unit. NMR and volatile product analysis confirm that degradation occurs largely at the dioxole unit leading to an array of new chain-end species. Main-chain and chain-end carbon-centered radicals were identified as arising from abstraction reactions and main-chain cleavage, respectively. In addition to loss of the dioxole units, XPS analysis indicates extensive char formation at the film surface, providing evidence of loss of fluorine atoms which in turn may react with free radical intermediates to form stable products identified by NMR. The implications for design of materials for 157 nm photolithography are discussed.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 67217-55-4. Category: dioxoles.

Methyl vinyl carbonyl oxide is an important intermediate in the reaction of isoprene and ozone and may be responsible for most of the (OH)-O-center dot formed in isoprene ozonolysis. We use CBS-QB3 calculations and RRKM/ master equation simulations to characterize all the pathways leading to the formation of this species, all the interconversions among its four possible conformers, and all of its irreversible isomerizations. Our calculations, like previous studies, predict (OH)-O-center dot yields consistent with experiment if thermalized syn-methyl carbonyl oxides form (OH)-O-center dot quantitatively. Natural bond order analysis reveals that the vinyl group weakens the C=O bond of the carbonyl oxide, making rotation about this bond accessible to this chemically activated intermediate. The vinyl group also allows one conformer of the carbonyl oxide to undergo electrocyclization to form a dioxole, a species not previously considered in the literature. Dioxole formation, which has a CBS-QB3 reaction barrier of 13.9 kcal/mol, is predicted to be favored over vinyl hydroperoxide formation, dioxirane formation, and collisional stabilization. Our calculations also predict that two dioxole derivatives, 1.2-epoxy-3-butanone and 3-oxobutanal, should be major products of isoprene ozonolysis.

An addition-cyclization reaction of nitroalkane anions with tricyclic o-quinones occurs in acetonitrile to yield the corresponding 1,3-dioxole derivatives. The heat of formation of the charge-transfer complex formed between the 2-nitropropane anion and 1,7-phenanthroline-5,6-dione is of greater magnitude than the observed activation enthalpy of the addition reaction. Since such a relationship could only arise when the charge-transfer complex lies along the reaction pathway, the charge-transfer complex acts as a real intermediate rather than a bystander in the addition reaction of the 2-nitropropane anion with the o-quinone derivative. A comparison of the observed rate constants with those predicted for the electron transfer from nitroalkane anions to o-quinones indicates that the addition reaction proceeds via electron transfer in the charge-transfer complex formed between nitroalkane anions and the o-quinones, followed by C-O adduct formation and subsequent cyclization to afford the 1,3-dioxole derivatives.

Permeability coefficients of hydrogen sulfide in fluorinated polymers are anomalously low when compared to its permeability in nonfluorinated polymers. As a result, fluoropolymer membranes have unusual selectivities for gas pairs involving H2S. For example, while the mixture CO2/H2S selectivity is 0.66 for nonfluorinated, rubbery poly( dimethylsiloxane), this selectivity is 8.0 for a fluoroelastomer composed of tetrafluoroethylene, perfluoromethyl vinyl ether, and perfluoro-8-cyano-5-methyl-3,6-dioxa-1-octene (TFE/PMVE/ 8CNVE) and 27 for a glassy, cyclic perfluoroether (Cytop) under similar test conditions. The low H2S permeability in fluoropolymers is caused primarily by unexpectedly low H2S solubility in the fluorinated polymer matrices. For instance, H2S solubility in a Teflon AF copolymer of tetrafluoroethylene and 2,2-bis(trifluoromethyl)-4,5difluoro- 1,3-dioxole is approximately 5 times lower than the value predicted by a correlation of solubility with gas critical temperature. This low solubility is not related to penetrant size or condensability effects but rather is caused by unfavorable molecular interactions between H2S and fluoropolymers. As a result of this unusual solubility behavior, fluorinated glassy polymers are more resistant to H2S-induced plasticization than nonfluorinated glasses. These findings may prove useful in emerging membrane applications that involve H2S, such as natural gas treatment.

Using 6-benzo[1,3]dioxolefulvene (1a), a series of benzodioxole substituted titanocenes was synthesized. The benzyl-substituted titanocene bis[(benzo[1,3]dioxole)-5-methylcyclopentadienyl] titanium (IV) dichloride (2a) was synthesized from the reaction of Super Hydride with 1a. An X-ray determined crystal structure was obtained for 2a. The ansa-titanocene (1,2-di(cyclopentadienyl)1,2-di-(benzo[1,3]dioxole)-ethanediyl) titanium(IV) dichloride (2b) was synthesized by reductive dimerisation of la with titanium dichloride. The diarylmethyl substituted titanocene bis(di(benzo[1,3]dioxole)-S-methylcyclopentadienyl) titanium(IV) dichloride (20 was synthesized by reacting la with the para-lithiated benzodioxole followed by transmetallation with titanium tetrachloride. When titanocenes 2a-c were tested against pig kidney (LLC-PK) cells inhibitory concentrations (IC50) of 2.8 X 10(-4), 1.6 x 10(-4) and 7.6 x 10(-5) m, respectively, were observed. These values represent improved cytotoxicity against LLC-PK, when compared with unsubstituted titanocene dichloride, but are not as impressive as values obtained for titanocenes previously synthesized using the above methods.

A medium size and rigid molecule (2,3-naphto-1,3-dioxole) has been selected for this study because full anisotropic reorientation is expected and because its symmetry elements dictate the orientation of the rotation-diffusion tensor. NMR measurements include direct cross-relaxation rates (which yield the three rotation-diffusion coefficients by assuming the length of CH bonds) and remote cross-relaxation rates (which, by using these rotation-diffusion coefficients, yield distances between a given carbon and remote protons). Two different solvents have been used: carbon disulfide and dimethyl sulfoxide, In both solvents, the same type of reorientation anisotropy is observed although with different ratios of rotation-diffusion coefficient values, presumably due to specific intermolecular interactions undergone by the dioxole ring. This would also explain geometrical variations at the level of this moiety. (C) 2002 Published by Elsevier Science B.V.
