(eta(5)-C5Me5)(2)U(=P-2,4,6-(Bu3C6H2)-Bu-t)(OPMe3) Revisited-Its Intrinsic Reactivity toward Small Organic Molecules

The Lewis base stabilized uranium phosphinidene (eta(5)-C5Me5)(2)U(=P-2,4,6-(Bu3C6H2)-Bu-t)(OPMe3) (2), which was derived from (eta(5)-C5Me5)(2)U(Cl)Me (1) and 2,4,6-(Me3C)(3)C6H2 PHK in toluene in the presence of Me 3 PO, was originally reported in 1996, but since then its reactivity toward small organic molecules has not been extensively explored. This contribution closes this gap, and divergent reactivity patterns are established in the reaction of complex 2 toward (small) organic substrates. For example, complex 2 may release the phosphinidene moiety (2,4,6-(Bu3C6H2P)-Bu-t:) and therefore may act as a source of a (eta(5)-C5Me5)(2)U-II fragment in the presence of Ph2S2, Ph2Se2, bipy, ketazine (Ph2C=N)(2), and conjugated alkynes RC CC CR, forming the disulfido compound (eta(5)-C5Me5)(2) U(SPh)(2) (5), diselenido compound (eta(5)-C5Me5)(2) U(SePh)(2) (6), bipy compound (eta(5)-C5Me5)(2) U(bipy) (8), diiminato compound (eta(5)-C5Me5)(2) U(N=CPh2)(2) (9) and the metallacyclopentatrienes (eta(5)-C5Me5)(2) U[te-C-4(R)(2)] (R = Ph (10), Me3Si (11)), respectively. Furthermore, compound 2 may also straightforwardly react with terminal alkynes and a variety of heterounsaturated (organic) molecules such as CS2, isothiocyanates, imines, diazenes, carbodiimides, nitriles, isonitriles, and organic azides. For instance, on treatment with phenylacetylene (PhC CH) the dialkynyl uranium complex (eta(5)-C5Me5)(2) U(C2Ph)(2) (OPMe3) (12) is formed, whereas CS2 and PhNCS furnish the carbodithioates (eta(5)-C5Me5)(2) U[SC(=P-2,4,6-Bu3C6H2)S](OPMe3) (13) and (eta(5)-C5Me5)(2) U[SC(=–NPh)S](OPMe3) (14), respectively. In the reaction of the secondary aldimine PhCH= NPh or the diazene PhN=NPh and 2 the uranium(IV) imido complex (q(5)-O5Me5)(2) U(=NPh)(OPMe3) (15) is isolated, which is in contrast to its reactivity with the primary ketimine 9-(C12H g )C=NH and the carbodiimides (RN=)(2)C, yielding the diiminato uranium(VI) complex (eta(5)-C5Me5)(2) U[N=C(C12H8)](2) (16) and the four-membered uranaheterocycles (eta(5)-C5Me5)(2) U[N(R)C(=P-2,4,6-(Bu3C6H2)-Bu-t)N(R)] (R = C6H11 (17), Pr (18)), respectively. Furthermore, treatment of 2 with nitriles RCN affords the imido uranium(IV) complexes (eta(5)-C5Me5)(2) U[=NC(=P-2,4,6-(Bu3C6H2)-Bu-t)R](OPMe3) (R = C6H11(19), Me3C (20)), whereas isonitriles RNC furnish the metallaaziridines (eta(5)-C5Me5)(2) U[C(=P-2,4,6-(Bu3C6H2)-Bu-t)N(R)1(OPMe3) (R = C6H11 (21), 2,6-Me2Ph (22)). However, in the reaction with organic azides RCN3, complex 2 yields the imido uranium(IV) complexes (eta(5)-C5Me5)(2) U(= NR)(OPMe3) (R = Ph3C (23), p-tolyl (24)) as a result of 3,3-Me-2-5,7-(Bu2C8H5P)-Bu-t (7) formation and N-2 release. The new compounds 12-24 were characterized by various spectroscopic techniques, including single-crystal X-ray diffraction analyses. Furthermore, with complex 2 in hand a comparison between the reactivity of uranium phosphinidenes differing in the steric bulk of its cyclopentadienyl ligands and the effects of a Lewis base (OPMe3) adduct was undertaken.

The Hallmarks of Copper Single Atom Catalysts in Direct Alcohol Fuel Cells and Electrochemical CO2 Fixation

Single-atom catalysts (SACs) are highly enviable to exploit the utmost utilization of metallic catalysts; their efficiency by utilizing nearly all atoms to often exhibit high catalytic performances. To architect the isolated single atom on an ideal solid support with strong coordination has remained a crucial trial. Herein, graphene functionalized with nitrile groups (cyanographene) as an ideal support to immobilize isolated copper atoms G(CN)-Cu with strong coordination is reported. The precisely designed mixed-valence single atom copper (G(CN)-Cu) catalysts deliver exceptional conversions for electrochemical methanol oxidation (MOR) and CO2 reduction (CO2RR) targeting a closed carbon cycle. An onset of MOR and CO2RR are obtained to be approximate to 0.4 V and approximate to-0.7 versus Ag/AgCl, respectively, with single active sites located in an unsaturated coordination environment, it being the most active Cu sites for both studied reactions. Moreover, G(CN)-Cu exhibited significantly lower resistivity and higher current density toward MOR and CO2RR than observed for reference catalysts.

Studies on the oxidation of 2,2,4-trisubstituted 3-pyrrolines

As part of our studies directed towards a total synthesis of lactacystin, we have developed a reliable and environmentally acceptable method to oxidise 2,2,4-trisubstituted 3-pyrrolines to the corresponding 3-pyrrolin-2-ones. Several protocols were examined and the two-step (i) TPAP/NMO; (ii) sodium hypochlorite allylic oxidation was found to be the most satisfactory. Catalytic oxidation of the 3-pyrroline afforded the corresponding cyclic imine in high yield, and subsequent oxidation with NaOCl afforded the N-chloro-3-pyrrolin-2-one. The N-chloro-substituent was removed by a simple acid treatment. (C) 2002 Published by Elsevier Science Ltd.

Microwave-induced free radicals production in red wine and model wine by electron paramagnetic resonance spin trapping

Microwave can directly induce the production of 1-hydroxyethyl free radical in red wine and model wine. Free radicals are considered as key intermediates in the wine aging processing by microwave, but their properties have not been determined. Electron paramagnetic resonance (EPR) spin trapping with 5,5-dimethyl-1-pyrrolin N-oxide (DMPO) was used to detect the type of free radicals. After microwave irradiation, spin adducts of hydroxyl free radical were detected in DMPO solution, whereas 1-hydroxyethyl free radical spin adducts were captured in red wine and model wine, because 1-hydroxyethyl free radicals arose from the oxidation of ethanol by hydroxyl free radical in red wine induced by microwave irradiation. Compared with the processing of natural oxidation, the intensity of free radicals induced by microwave in red wine became more strong, and the effects of microwave temperature, time, and power on the intensity of 1-hydroxyethyl free radical spin adducts in model wines were also studied. The intensity of free radical spin adducts increased with the increasing of microwave power and time. The intensity of DMPO/1-hydroxyethyl free radical spin adducts increases at low temperature, but decreased at higher temperatures. Practical applications This study investigated the existence of free radical in the processing of wine aging, and the possible mechanism of microwave irradiation accelerated aging of red wine was studied with model wine. Results revealed that the intensity of 1-hydroxyethyl free radical induced by microwave in red wine and model wine. Therefore, microwave irradiation was considered to be a promising aging technology, so microwave radiation technology can be used in many aging products that sped up the aging processing.

A Comparison Study on Reinforcement Behaviors of Functional Fillers in Nitrile Rubber Composites

To investigate the reinforcing effects of functional fillers in nitrile rubber (NBR) materials, high-structure carbon black (HS45), coated calcium carbonate (C-CaCO3), silica (200MP), and multi-walled carbon nanotubes (MWCNTs) were used as functional filler, and carbon black (SRF) as a common filler were used for oil-resistant rubber. The curing and mechanical properties of HS45-, 200MP-, and MWCNT-filled NBR compounds were improved compared to those of the SRF-filled NBR compound. The reinforcing effect also increased with a decrease in the particle size of the fillers. The C-CaCO3-filled NBR compound exhibited no reinforcing effect with increasing filler concentration because of their large primary particle size (2 mu m). The reinforcing behavior based on 100% modulus of the functional filler based NBR compounds was compared by using several predictive equation models. The reinforcing behavior of the C-CaCO3-filled NBR compound was in accordance with the Smallwood-Einstein equation whereas the 200MP- and MWCNT-filled NBR compounds fitted well with the modified Guth-Gold (m-Guth-Gold) equation. The SRF- and HS45-filled NBR compounds exhibited reinforcing behavior in accordance with the Guth-Gold and m-Guth-Gold equations, respectively, at a low filler content. However, the values of reinforcement parameter (100M(f)/100M(u)) of the SRF- and HS45-filled NBR compounds were higher than those determined by the predictive equation model at a high filler content. Because the chains of SRF composed of spherical filler particles are similarly changed to rod-like filler particles embedded in a rubber matrix and the reinforcement parameter rapidly increased with a high content of HS45, the higher-structured filler. The reinforcing effectiveness of the functional fillers was numerically evaluated on the basis of the effectiveness index (phi(SRF)/phi(f)) determined by the ratio of the volume fraction of the functional filler (phi(f)) to that of the SRF filler (phi(SRF)) at three unit of reinforcing parameter (100M(f)/100M(u)). On the basis of their effectiveness index, MWCNT-, 200MP-, and HS45-filled compounds showed higher reinforcing effectiveness of 420%, 70%, and 20% than that of SRF-filled compound, respectively whereas C-CaCO3-filled compound exhibited lower reinforcing effectiveness of -50% than that of SRF-filled compound.

The effects of fiber silane modification on the mechanical performance of chopped basalt fiber/ABS composites

The purpose of this study was to examine the effects of silane coupling agent modifications on the mechanical performance of the basalt fiber (BF)-reinforced acrylonitrile-butadiene-styrene (ABS) composites. Three different silane coupling agents were used. The mechanical properties of the composites were determined by the tensile, flexural, impact tests, and dynamic mechanical analysis (DMA). According to the test results, the tensile strength increased with the use of (3-aminopropyl) triethoxysilane (AP) and 3-(trimethoxysilyl) propylmethacrylate (MA), while the use of (3-glycidyloxypropyl) trimethoxysilane (GP) reduced the tensile strength. All the silane modifications improved the flexural strength and modulus and the highest improvement was achieved with the use of AP. No remarkable difference was observed in impact properties with the use of silane coupling agents. The addition of BF significantly improved the elastic modulus of the ABS regardless of the modification type, while the further improvements were achieved through the use of AP and MA. In brief, AP showed the highest performance among the studied silane coupling agents due to the covalent bond formation between the amino group of AP and the nitrile group of styrene-acrylonitrile (SAN) matrix.
