A post-synthetically reduced borane-functionalised metal-organic framework with oxidation-inhibiting reactivity

The first post-synthetic reduction of a ketone-containing metal-organic framework (MOF) is reported. The borane tetrahydrofuran complex (H3B center dot THF) quantitatively reduced a ketone functional group in a porous zinc(II) IRMOF-9 scaffold at room temperature. Single crystal X-ray diffraction studies established that the crystallinity and interpenetration mode of the framework are preserved during reduction. Boron remains bound in the framework and can be removed via mild acid treatment to yield a MOF with identical properties to that prepared by direct synthesis. The boron-functionalised MOF was unable to reduce benzaldehyde but instead was found to inhibit benzaldehyde autooxidation.

Emergence of 2,3,5-trisubstituted tetrahydrofuran natural products and their synthesis

The emergence of various 2,3,5-trisubstituted tetrahydrofuran natural products in the recent literature and their synthesis is the focus of this review. These molecules exhibit varied bioactivities and have garnered the interest of several synthetic chemists owing to their efficient synthesis. A few of them have been synthesized and their absolute stereo structure has been confirmed for the first time. These will be appealing candidates in future synthetic investigations along with the untouched molecules. Thus, this compilation will reveal these molecules for expansion of their diversity within the realm of both synthesis and bioactivity studies.

Origin of Bond Elongation in a Uranium(IV) cis-Bis(imido) Complex

The activation of U-N multiple bonds in an imido analogue of the uranyl ion is accomplished by using a system that is very electron-rich with sterically encumbering ligands. Treating the uranium(VI) trans-bis(imido) UI2(NDIPP)(2)(THF)(3) (DIPP = 2,6-diisopropylphenyl and THF = tetrahydrofuran) with tert-butyl(dimethylsilyl)amide (NTSA) results in a reduction and rearrangement to form the uranium(IV) cis-bis(imido) [U(NDIPP)(2)(NTSA)(2)]K-2 (1). Compound 1 features long U-N bonds, pointing toward substantial activation of the N=U=N unit, as determined by X-ray crystallography and H-1 NMR, IR, and electronic absorption spectroscopies. Computational analyses show that uranium(IV)-imido bonds in 1 are significantly weakened multiple bonds due to polarization toward antibonding and nonbonding orbitals. Such geometric control has important effects on the electronic structures of these species, which could be useful in the recycling of spent nuclear fuels.

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 108-55-4, in my other articles.

Suppression of methane hydrate dissociation from SDS-dry solution hydrate formation system by a covering liquid method

Prevention of gas hydrate dissociation made potential application of gas storage and transportation by hydrate-based technology. In this work, a covering liquid method was proposed to prevent methane (CH4) hydrate dissociation when methane hydrate formed in sodium dodecyl sulfate (SDS)-dry solution system. The covering liquids were cyclopentane (CP), cyclohexane, and tetrahydrofuran (THF), respectively. The results showed that CP and THF can effectively prevent methane hydrate dissociation at 266.0 K, while cyclohexane failed to prevent methane hydrate dissociation at the same temperature. Methane hydrate dissociated percentage was 25.5% (0.61 MPa) after 12 h of dissociation at 266.0 K, which can be reduced to 20.0% (0.24 MPa) and 13.8% (0.30 MPa) by covering CP and THF, respectively. All three covering liquids can prevent methane hydrate dissociation at 272.2 K, and methane hydrate dissociated percentage decreased from 71.1% (1.33 MPa) without covering liquid to 49.1% (0.82 MPa), 36.4% (0.64 MPa), and 30.4% (0.63 MPa) by covering CP, cyclohexane, and THF, respectively. However, when methane hydrate dissociated temperature increased to 274.2 K, all three covering liquids failed to prevent initial methane hydrate dissociation, but suppressed later stage of methane hydrate dissociation by forming binary hydrate.

Non-porous organic crystals and their interaction with guest molecules from the gas phase

Some organic molecules encapsulate solvents upon crystallization. One class of compounds that shows a high propensity to form such crystalline solvates are tetraaryladamantanes (TAAs). Recently, tetrakis(dialkoxyphenyl)-adamantanes have been shown to encapsulate a wide range of guest molecules in their crystals, and to stabilize the guest molecules against undesired reactions. The term ‘encapsulating organic crystals’ (EnOCs) has been coined for these species. In this work, we studied the behavior of three TAAs upon exposition to different guest molecules by means of sorption technique. We firstly measured the vapor adsorption/desorption isotherms with water, tetrahydrofuran and toluene, and secondly, we studied the uptake of methane on dry and wet TAAs. Uptake of methane beyond one molar equivalent was detected for wet crystals, even though the materials showed a lack of porosity. Thus far, such behavior, which we ascribe to methane hydrate formation, had been described for porous non-crystalline materials or crystals with detectable porosity, not for non-porous organic crystals. Our results show that TAA crystals have interesting properties beyond the formation of conventional solvates. Gas-containing organic crystals may find application as reservoirs for gases that are difficult to encapsulate or are slow to form crystalline hydrates in the absence of a host compound.

An electrode-level prelithiation of SiO anodes with organolithium compounds for lithium-ion batteries

Silicon monoxide (SiO) is considered an attractive alternative to conventional graphite anodes due to its high specific capacity and good cycling performance. However, it suffers from low initial Coulombic efficiency (ICE) due to a large irreversible capacity and large volume change during cycling. Both deficiencies hinder the commercial use of SiO anodes. A new organolithium compound (Li-9,9-dimethyl-9H-fluorene-tetrahydrofuran) with lower redox potential is reported to prelithiate a SiO-based anode. An SEI layer is formed during prelithiation and a controllable amount of reversible lithium is preloaded into the SiO electrode. The ICE of a prelithiated SiO-based electrode in half-cell format is increased greatly to similar to 90.7%. When matched with a LiNi0.6Co0.2Mn0.2O2 cathode, the full cell with the prelithiated SiO/G anode exhibits a much improved ICE in comparison with the pristine one (87.1% vs. 61.1%). This facile prelithiation method is proved to be a practical solution for the commercial application of SiO-based materials.

Bromelain Immobilized onto Diamine-functionalized Electrospun Polyvinyl Chloride Fibers as a Durable Heterogeneous Catalyst

The best condition to produce smooth polyvinyl chloride (PVC, M.W. similar to 6.4×10(4) g/mol) fibers (572 +/- 171 nm) was 10 % w/v PVC in a mixture of tetrahydrofuran and dimethyl sulfoxide (4:1 by volume) with 5 % w/w Tween 20, 15 kV, 10 cm, and 3 ml/h. PVC fibers were subjected to plasma surface treatment to make them more hydrophilic. Diameters of the treated fibers were 549 +/- 99 nm. Next, the PVC fibers were treated with ethylene diamine (EDA) and p-phenylenediamine (PDA) to obtain PVC-EDA and PVC-PDA, respectively. Bromelain was immobilized onto PVC-EDA and PVC-PDA by an aid of 1 % w/v glutaraldehyde to receive PVC-EDA-bromelain and PVC-PDA-bromelain with good tensile strengths of similar to 19 and similar to 14 MPa, respectively. The activities of free and immobilized bromelain were assayed by casein as a substrate and a spectrophotometer at 275 nm. Bromelain loadings on PVC-EDA-bromelain and PVC-PDA-bromelain were 88.10 +/- 3.54 and 36.38 +/- 18.10 mg/g of fibers, respectively. The kinetic activities of bromelain, PVC-EDA-bromelain, and PVC-PDA-bromelain were 11.31 +/- 2.17, 0.31 +/- 0.03, and 2.15 +/- 1.34 min(-1), respectively. PVC-EDA-bromelain and PVC-PDA-bromelain could be reused at least 9 times with > 50 % relative activities and endured heat (50-90 degrees C) better than free bromelain did. Their relative activities were > 70 % after storage at 90 degrees C for 20 min.

Studies of FeSe(2)Cathode Materials for Mg-Li Hybrid Batteries

Rechargeable magnesium (Mg)-based energy storage has attracted extensive attention in electrochemical storage systems with high theoretical energy densities. The Mg metal is earth-abundant and dendrite-free for the anode. However, there is a strong Coulombic interaction between Mg(2+)and host materials that often inhibits solid-state diffusion, resulting in a large polarization and poor electrochemical performances. Herein, we develop a Mg-Li hybrid battery using a Mg-metal anode, an FeSe(2)powder with uniform size and a morphology utilizing a simple solution-phase method as the counter electrode and all-phenyl-complex/tetrahydrofuran (APC)-LiCl dual-ion electrolyte. In the Li+-containing electrolyte, at a current density of 15 mA g(-1), the Mg-Li hybrid battery (MLIB) delivered a satisfying initial discharge capacity of 525 mAh g(-1). Moreover, the capacity was absent in the FeSe2|APC|Mg cell. The working mechanism proposed is the Li+-only intercalation at the FeSe(2)and the Mg(2+)dissolved or deposited at the Mg foil in the FeSe2|Mg2+/Li+|Mg cell. Furthermore, ex situ XRD was used to investigate the structural evolution in different charging and discharging states.

Design, synthesis, and structure – Activity relationship, molecular modeling, and NMR studies of a series of phenyl alkyl ketones as highly potent and selective phosphodiesterase-4 inhibitors

Phosphodiesterase 4 catalyzes the hydrolysis of cyclic AMP and is a target for the development of anti-inflammatory agents. We have designed and synthesized a series of phenyl alkyl ketones as PDE4 inhibitors. Among them, 13 compounds were identified as having submicromolar IC50 values. The most potent compounds have IC50 values of in the mid- to low-nanomolar range. Compound 5v also showed preference for PDE4 with selectivity of >2000-fold over PDE7, PDE9, PDE2, and PDE5. Docking of 5v, 5zf, and 5za into the binding pocket of the PDE4 catalytic domain revealed a similar binding profile to PDE4 with rolipram except that the fluorine atoms of the difluoromethyl groups of 5v, 5za, and 5zf are within a reasonable range for hydrogen bond formation with the amide hydrogen of Thr 333 and the long alkyl chain bears additional van der Waals interactions with His 160, Asp 318, and Tyr 159.
