Pulse field gradient diffusion measurements were made on the decafluoropentane molecule, CF3CHFCHFCF2CF3, in the copolymer of tetrafluoroethylene (TFE) and 2,2-bis(trifluoromethyl)-4,5-difluoro-1,3-dioxole (BDD). The proton spectrum consisted of two overlapping line shapes, and the decay of the echo amplitude with increasing gradient required the use of two apparent diffusion constants. The two apparent diffusion constants differed by 1.5-3 orders of magnitude depending on the length of time over which diffusion occurred. Both apparent diffusion constants were also functions of the diffusion time, indicating the presence of structure in this system that obstructs the translational motion of the penetrant molecules. The slower diffusion process ranged from 10(-8) to 10(-10) cm(2) s(-1), while the faster diffusion process ranged from 10(-6) to 10(-8) cm(2) s(-1). The product of the slower diffusion constant and the diffusion time was constant within experimental error, which is typical of restricted diffusion. Assuming a spherical geometry, the length scale was 0.7 mum. The fast diffusion constant appeared to decrease toward a plateau at large diffusion times, which is typical of tortuous diffusion in a porous medium. The slower diffusion process was considered to involve molecules in low-free-volume regions as this process was associated with the broader proton resonance and a longer spin-lattice relaxation time. The faster diffusion process was considered to involve penetrant molecules in high-free-volume regions that were interconnected. A narrower resonance with a shorter spin-lattice relaxation time was associated with this process.

Behavioral effects of 5-{3-[((2S)-1,4-benzodioxan-2ymethyl)amino]propoxy}-1,3-benzo- dioxole HCI (MKC-242), a novel 5-HT1A-receptor agonist, were evaluated using animal models of anxiety and obsessive compulsive disorder and compared against reference compounds. MKC-242 suppressed foot shock-induced fighting behavior without loss of motor coordination in mice as the reference compounds did. The ED50 values of MKC-242, buspirone, tandospirone and diazepam were 1.7, 42, 80 and 2.0 mg/kg, p.o., respectively. The duration of the suppression of fighting by MKC-242 was longer than those of buspirone and tandospirone and comparable to that of diazepam. Similar results were also obtained with the water-lick conflict test in rats. The plasma concentration of MKC-242 in rats was much higher than the reported value of buspirone during 0.25-6 hr after oral administration. In addition, MKC-242 reduced marble burying behavior without reduction of motor activity. Fluoxetine, tandospirone and diazepam also reduced the behavior at non-sedative doses. These findings indicate that MKC-242 possesses a longer-lasting anxiolytic effect than azapirones. This might be due to the high concentration of the compound in plasma. In addition, it is also suggested that MKC-242 possesses an antiobsessional effect.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 29390-67-8, you can contact me at any time and look forward to more communication. Category: dioxoles.

Methyl 2-iodobenzoates 1a-c undergo cyclization reactions with various aromatic aldehydes 2 a-m (RC6H4CHO: R=H 2a, 4-CH3 2b, 4-tBu 2 c, 4-OMe 2 d, 3-OMe 2 e, 4-Cl 2 f, 4-CF3 2g, 4-CN 2h, 4-Ph 2i; benzo[d][1,3]dioxole-5-carbaldehyde (2j), -napthaldehyde (2k), benzofuran-2-carbaldehyde (21), and isonicotinaldehyde (2m)) in the presence of [CoI2(dppe)] (dppe = 1,2-bis(diphenylphosphino)ethane) and Zn powder in dry THF at 75 degrees C for 24 h to give the corresponding phthalide derivatives 3a-m and 3q-t in good to excellent yields. Under similar reaction conditions, less reactive aliphatic aldehydes, heptanal (2n), butyraldehyde (2o), and 2-phenylacetaldehyde (2p) also underwent cyclization reactions with la to provide 3n-p, respectively, in fair to good yields. The catalytic reaction can be further extended to cinnamyl aldehyde (2q) with la to give the corresponding phthalide derivative 3u. This synthetic method is compatible with a variety of functional groups on the aryl ring of 2. The high efficiency of the cobalt catalyst containing a dppe (dppe=1,2-bis(diphenylphosphino)ethane) ligand encouraged us to investigate the asymmetric version of the present catalytic reaction by employing bidentate chiral ligands. Thus, aromatic aldehydes 2a-c, 2f, and 2g undergo cyclization with 2-iodobenzoate (1a) smoothly in the presence of [CoI2(S,S)-dipamp}] ((SS)-dipamp(1S,2S)-(+)-bis[2-methoxyphenyl]phenylphosphino)ethane) and zinc powder in THF at 75 degrees C for 24 h, giving the corresponding (S)-phthalides 4a-e in 81-89% yields with 70-98% ee. A possible mechanism for the present catalytic reaction is proposed.

Ultrafast mid-infrared (IR) spectroscopy is used to monitor chemical reactions initiated by flash-heating a nanoenergetic material consisting of 30 nm diameter Al nanoparticle fuel in a Teflon(AF) oxidizer. Teflon(AF) is a copolymer of tetrafluoroethylene (TFE) and 2,2-bis(trifluoromethyl)-4,5-difluoro-1,3-dioxole (dioxole), so Al can react with several different moieties. Transitions associated with CF2 stretching of TFE or CFO stretching or CF3 stretching of dioxole were monitored. The reactions of Al with CFO occurred with time constant (k(1))(-1) = 50 (+/- 20 ps); reactions of Al with CF2 or CF3 were more than 10 times slower, (k(2))(-1) = 0.7 (+/- 0.05 ns). An interesting frequency oscillation is seen in the 1148 cm(-1) band, where the peak frequency undergoes a time-dependent shift from 1148 to 1155 cm(-1) and then back to 1148 cm(-1). Due to the coincidence of CFO and CF2 stretching transitions, this band in the copolymer represents an amalgamated vibration with amplitude on both TFE and dioxole. As concentration is varied from pure dioxole to pure TFE, the band blue-shifts. A kinetic scheme and a model for the concentration dependence of the amalgamated vibration frequency are developed, which show that the frequency oscillation is a consequence of the arrangement of reactants on the nanoscale, which creates two types of oxidizer. The type adjacent to the Al nanoparticle is in a region of high local fuel concentration, while the other type is too distant from the fuel to react.

A series of copolymers of tetrafluoroethylene and 4-trifluormethoxy-1,3-perfluorodioxole (TFETFMD) were prepared as well as a homopolymer of the dioxole (TEMD) using various free-radical initiators. The copolymers were characterized by F-19 NMR, TGA, DSC and VUV measurements. The transparency at 157nm increased with increasing dioxole content reaching an alpha (mum(-1)) = 0.76 for an unoptimized homopolymer of the dioxole prepared with a perfluorinated peroxide initiator. Exposure studies of the dioxole homopolymer at 157 nm indicate rapid formation of carbonyl species and therefore an anticipated short lifetime as a potential polymer pellicle for 157 nm lithography.

A highly selective nitric oxide (NO) sensor is fabricated and applied to devise an enhanced flow injection analysis (FIA) system for S-nitrosothiols (RSNOs) measurement in biological samples. The NO sensor is prepared using a polytetrafluoroethylene (PTFE) gas-permeable membrane loaded with Teflon AF (R) solution, a copolymer of tetrafluoroethylene and 2,2-bis(trifluoroethylene)-4,5-difluoro-1,3-dioxole, to improve selectivity. This method is much simpler and possesses good performance over a wide range of RSNOs concentrations. Standard deviation for three parallel measurements of blood plasma is 4.0%. The use of the gas sensing configuration as the detector enhances selectivity of the FIA measurement vs. using less selective electrochemical detectors that do not use PTFE/Teflon type outer membranes.

Search and development of new effective antioxidant molecules with improved activity is of both biological and commercial importance. In this background, we have modeled antioxidant activities of a series of benzodioxoles for their ability to inhibit lipid peroxidation (pC) using quantitative structure activity relationship (QSAR) technique. The QSAR models were developed using different chemometric tools such as GFA and G/PLS techniques. Two different sets of descriptors were used for developing these QSAR models. Molecular shape analysis (MSA) and spatial (charged partial surface area and shadow) descriptors were included in the one set, whereas quantum chemical (Mulliken charges on common atoms of the molecules calculated at the AMI level) and physicochemical (hydrophobic parameter and molar refractivity) descriptors were included in the other set. All the models developed were validated internally by leave-one-out cross-validation and randomization techniques. The model predictivity was judged by their cross-validated squared correlation coefficient (Q(2)) and the modified r(2) (r(m)((LOO))(2) ) values, whereas the robustness of the models was judged from the value of R-p(2) (Roy and Paul. QSAR Comb Sci DOI: 10.1002/qsar.200810130). The developed models suggest that the antilipid peroxidative activity of the molecules largely depends on the charges of the carbon atoms connected to the oxygen atoms of the dioxole ring. Besides this, the activity also depends oil the charged surface area of the molecules and the dipole moment of the molecules. Presence of the methoxy substituents (ortho or meta) oil the phenyl ring at the R, position of the benzodioxoles significantly lowers the antioxidant activity of these molecules.
