We have successfully synthesized the thienoselenadiazole unit through the condensation reaction between thiophene diamine and SeO₂ and applied the thienoselenadiazole unit for D-A-conjugated polymers. The thienoselenadiazole-based polymers exhibit good solubility in common organic solvents, good thermal stability, and deep HOMO levels. The solar cells based on thienoselenadiazole-containing polymers gave high open-circuit voltage. Further improving of the light-absorption properties of the thienoselenadiazole-containing polymers to achieve high short-circuit c.d. and high power conversion efficiency is currently underway.

Greedy, Benjamin M. published the artcileOrvinols with Mixed Kappa/Mu Opioid Receptor Agonist Activity, Computed Properties of 18928-94-4, the publication is Journal of Medicinal Chemistry (2013), 56(8), 3207-3216, database is CAplus and MEDLINE.

Dual-acting kappa opioid receptor (KOR) agonist and mu opioid receptor (MOR) partial agonist ligands have been put forward as potential treatment agents for cocaine and other psychostimulant abuse. Members of the orvinol series of ligands are known for their high binding affinity to both KOR and MOR, but efficacy at the individual receptors has not been thoroughly evaluated. In this study, it is shown that a predictive model for efficacy at KOR can be derived, with efficacy being controlled by the length of the group attached to C20 and by the introduction of branching into the side chain. In vivo evaluation of two ligands with the desired in vitro profile confirms both display KOR, and to a lesser extent MOR, activity in an analgesic assay suggesting that, in this series, in vitro measures of efficacy using the [³⁵S]GTPγS assay are predictive of the in vivo profile.

Hine, Jack published the artcileEffect of halogen atoms on the reactivity of other halogen atoms in the same molecule. IV. The mechanism of the transformation of vicinal dihalides to olefins by reaction with iodide ion, Computed Properties of 594-81-0, the publication is Journal of the American Chemical Society (1955), 361-4, database is CAplus.

cf. C.A. 48, 10531g. It is shown that the dehalogenation of (CH₂Br)₂, MeCHBrCH₂Br, and EtCHBrCH₂Br by iodide ions is largely initiated by an S_N2 attack to form a bromoiodide which is directly dehalogenated. The dehalogenation of the 2,3-dibromobutanes is believed to be largely direct, as previously suggested. In evidence is the fact that (CH₂Br)₂ is the most reactive of the dibromides mentioned. Furthermore it is shown that the rate constant for the reaction of (CH₂Br)₂ is in excellent agreement with that which would be predicted for the S_N2 reaction of the compound with iodide ion under the conditions employed. It is improbable that a very large fraction of the reaction follows a path involving the formation of a vicinal diiodide. It is proposed that the dehalogenation reaction proper involves the formation of an intermediate in which 1 of the halogen atoms is bound equally to 2 C atoms. F(CH₂)₂Br (about 0.01 mole) was weighed into about 48 cc. MeOH, the solution equilibrated at 40°, mixed with 50 cc. 0.1M KI in MeOH (40°), the mixture diluted to 100 cc., and the iodide ion concentration determined within a few min., by withdrawing a 5-cc. sample and titrating with KIO₃ in cold concentrated HCl; the rate constant was in 2 similar runs 5.49 ± 0.30 and 5.74 ± 0.06 × 10^-6 sec.^-1 mole^-1; no observable amount of iodine was formed in either run.

Haddad, Boumediene published the artcileSynthesis, NMR, vibrational spectroscopy, thermal and DFT studies of new DABCO hexafluorophosphate based ionic liquid, Computed Properties of 111-83-1, the publication is Journal of Molecular Structure (2022), 132682, database is CAplus.

In this paper, a new ionic liquid; [C₈DABCO⁺][PF^–₆] was prepared, its structure was well confirmed by ¹H, ¹³C, ¹⁹F and ³¹P-NMR spectroscopies. Besides, thermal behavior has been discussed through TGA and DTA in the temperature range from [-80 to 200°C] and [25 to 700°C] resp. Theor. studies were performed by DFT method to investigate the structural, electronic and topol. properties. B3LYP/6-31G* calculations support the high solvation energy value of IL in aqueous solution (ΔG_c= -122.9 kJ/mol) and it probably explain the high dipole moment value, the volume expansion in this medium (7.3 ų) and also because the cation-anion interactions still remain in solution Seven interactions were predicted by AIM calculations but only two cation-anion interactions have short distances. NBO studies reveal that IL is more stable in solution probably due to its higher solvation energy. The DOS spectrum in aqueous solution shows clearly that the orbitals belonging to the atoms of cage-like DABCO structure participle in both HOMO and LUMO and, hence, will confirm that DABCO is engaged in halogen interactions, as suggested from NBO analyses. These studies show that DABCO structure participates in the properties of [C₈DABCO⁺][PF^–₆]. Complete assignments of IR and Raman spectra were reported.

Braunschweig, Holger published the artcileSynthesis, Crystal Structure, EPR and DFT Studies, and Redox Properties of [2]Tetramethyldisilacobaltocenophane, Synthetic Route of 18346-57-1, the publication is Organometallics (2008), 27(24), 6427-6433, database is CAplus.

The 1st [2]silacobaltocenophane, [(Me₂Si)₂(η⁵-C₅H₄)₂Co] (1), was synthesized by dilithiation of 1,2-bis(cyclopentadienyl)-1,1,2,2-tetramethyldisilane with BuLi and subsequent reaction with [CoBr₂(dme)]. EPR spectroscopic studies of frozen pentane solutions of 1 at X-band showed a fully anisotropic g tensor (g₁ = 1.914, g₂ = 2.005, and g₃ = 2.084) with hyperfine couplings on all three components (A₁ = 145 MHz, A₂ = 67 MHz, and A₃ = 424 MHz). DFT studies using the B3LYP functional with its 20% exact exchange provide the best agreement with experiment and reproduce the g and A tensors well. Spin-orbit contributions to the isotropic coupling (A_PC) and to the anisotropies (A_i^dip,2) are significant. As was shown by cyclic voltammetry in THF, 1 is quasi-reversibly oxidized to the neutral cobaltocenium cation [(Me₂Si)₂(η⁵-C₅H₄)₂Co]⁺ (8) at a potential of E°_1/2 = -1.27 V (vs. the Fc/Fc⁺ couple) and quasi-reversibly reduced to the corresponding anion [(Me₂Si)₂(η⁵-C₅H₄)₂Co]^– (9) at E°_1/2 = -2.40 V. The preparative oxidation of 1 with 1 equiv of ferrocenium hexafluorophosphate ([Fc][PF₆]) provided the diamagnetic [PF₆]^– salt of the cation 8 in high yields. The mol. structures of both complexes (1 and 8) were confirmed by x-ray diffraction anal., and a significant decrease in mol. strain was depicted. DFT findings support the experiments

Russell, Glen A. published the artcileDirective effects in aliphatic substitutions. III. The photobromination of branched-chain hydrocarbons; the dark reaction of bromine with tertiary alkyl bromides, Recommanded Product: 2,3-Dibromo-2,3-dimethylbutane, the publication is Journal of the American Chemical Society (1955), 4025-30, database is CAplus.

The photobromination of hydrocarbons in the liquid phase is highly selective and constitutes an excellent method for the preparation of tertiary bromides from hydrocarbons which contain only primary and tertiary H atoms. The presence of secondary or an addnl. tertiary H atom in the adjacent position leads to the formation of considerable amounts of dibromides. It is proposed that these dibromides arise from an ionic or mol. reaction of Br with the tertiary bromide formed in the initial photochem. reaction. The dark reaction of Br with Me₃CBr exhibits 3rd order kinetics. No evidence could be obtained of a measurable equilibrium between olefin and hydrogen halide in solutions of Me₃CBr and Me₃CCl in refluxing SO₂ or of Me₂CBrCMe₃ (XVII) in CCl₄ at 76°. Yet Br reacts rapidly with the tertiary halides under these conditions. These results are consistent with a reaction mechanism in which a Br mol. brings about the ionization of the tertiary bromide, followed by reaction of a 2nd Br mol. with the high-energy π-complex form of the carbonium ion. Me₃CCHMe₂ (XVIII), b₇₄₅ 80.3°, n_D²⁰ 1.3895 (1 mol) irradiated with a 150-w. clear light bulb (1 in. from the flask) and treated 1.5 h. with 0.25 mol Br at 80°, 25 g. XVIII distilled off, the residue cooled, and the nearly solid crystalline mass (57 g.) washed with 50 cc. cold XVIII gave 36 g. XVII, m. 149-50° (sealed tube), and 10 g. XVIII by vacuum sublimation at 80°/25 mm. Cumene (XIX) (1 mol), b₇₄₀ 151.4-5°, n_D²⁰ 1.4915, brominated similarly 0.5 h. with 0.5 mol Br at 60°, and the mixture bubbled with N to remove the HBr and analyzed for total and hydrolyzable Br (80% EtOH at 25°) showed that 73% of the Br was present as the tertiary bromide. A similar run with 0.25 mol Br/mol XIX gave during 1.5 h. at 0° a product containing 94% of the Br as tertiary bromide; the bromide could not be crystallized from the solution at -80° and attempts to distil below 1 mm. resulted in dehydrobromination. Br (0.5 mol) added under illumination to 0.5 mol XIX in CH₂Cl₂ at 0° until the Br color persisted 2 min. after the addition of 1 drop Br and the product rectified gave 111 g. MePhCBrCH₂Br, b₁₆ 120-20.5°. Br (0.5 mol) added to 2 mol (Me₂CH)₂ (XX), n_D²⁰ 1.3749, at 55° during 6 h. at such a rate that the hydrocarbon remained colorless through the reaction, the mixture cooled, and the crystalline deposit (65 g.) sublimed at 95-100°/5 mm. gave 54 g. (Me₂CBr)₂ (XXI), m. 169-71° (sealed tube). Br (0.5 mol) added dropwise at 60° during 8 h. to 2 mol Me₂CHPr (XXII), n_D²⁰ 1.3714, at such a rate that the solution was nearly colorless at all times, and the mixture fractionated gave 64 g. mixture of 92% Me₂CHBrPr and 8% secondary bromides from XXII, and 10 g. material, b₄₀ 92-2.5°, containing 64.5% Br, largely as Me₂CBrCHBrEt. XVII (0.075 mol) in 100 g. CCl₄ treated 40 h. at 25° with 0.076 mol dry Br, the CCl₄ removed, the mixture sublimed in vacuo to remove 2 g. unchanged XVII, and the residue distilled gave 10.3 g. dibromide, b₁₀ 88.5-9.5°, presumably BrCH₂CMeBrCMe₃, and 3 g. tribromides, b₃ 107-10°. Br (0.25 mol) and 0.25 mol Me₂CBrEt in 120 cc. CCl₄ held 40 h. at 25° in the dark and the mixture distilled gave 34 g. Me₂CBrCHBrMe, b₃₀ 72.5-73°, n_D²⁰ 1.5095, and 8.5 g. tribromide, b₁₅ 110-14°. Me₂C(OH)CHMe₂ (XXIII), b₁₀₀ 65.5, n_D²⁰ 1.4182, (10.2 g.) as a 2M solution in CCl₄ treated with Br 60 h. in the dark and the product crystallized and rectified gave 18.2 g. XXI, m. 168-9°, 2.1 g. unchanged XXIII, 1 g. tribromide, b₂₅ 140-50°, and traces of a lachrymator. A similar run with 16 g. Br and 10.2 g. XXIII in the presence of 10 g. finely divided CaCO₃ showed only 80% reaction of the Br in 72 h. and gave 10 g. dibromide, 5 g. XXIII, and 4 g. high-boiling material, presumably a tribromide. Me₃CBr (40 g.) and 46 g. Br held 42 h. at 0° in the dark and the mixture distilled gave 43 g. Me₂CBrCH₂Br, b. 146-9°, and 6 g. higher-boiling material, probably the tribromide. Br (15.984 and 13.700 g. Me₃CBr diluted to 100 cc. at 0° with CCl₄, 5-cc. samples sealed in ampuls, stored in ice, and 1-cc. aliquots titrated with standard Na₂S₂O₃ at appropriate intervals gave the kinetic data for the bromination; average k₃ × 10² l.²/mol²/h. 0.52. Photobrominations at 25° were carried out with 5 mol % solutions by degassing the appropriate hydrocarbon with N, vaporizing dry Br in a stream of N, passing the Br-N mixture during 1 h. into the hydrocarbon, removing the HBr with N, and analyzing the mixture (the Br used, the total bromide, and the tertiary bromide, all in moles, given): XIX, 0.055, 0.0541, 0.0541; XVIII, 0.050, 0.0486, 0.0457; XXII, 0.051, 0.0492, 0.0443; XX, 0.051, -, 0.0214 (some dibromide crystallized during the bromination); XX, 0.031, 0.0302, 0.0238; XX (0°), 0.038, 0.0371, 0.0326. Me₃CCl (5 cc.) added during 6 h. to 15 cc. SO₂ refluxing at -12.5 ± 0.5°, and 100 cc. vapor removed under standard conditions and analyzed in a mass spectrometer showed that not more than 0.001% Me₃CCl had been dehydrochlorinated. Me₃CBr (5 g.) treated 6 h. with 25 cc. SO₂ refluxing at -14 ± 0.5°/722 mm. was less than 0.001% dehydrobrominated. XVII (500 cc. 0.2M solution in CCl₄) rectified at atm. pressure, 400 cc. CCl₄ removed during 24 h., all gases formed passed into aqueous NaOH, and the distillate extracted with H₂O indicated the complete absence of acidic materials or bromide ion. Me₂CBrEt (5 cc.), 25 cc. CH₂Cl₂, and 2 g. iodine refluxed at such a pressure that the temperature was 25°, and 100 cc. vapor removed under a high reflux ratio during 6 h. and analyzed showed less than 0.001% dehydrobromination.
