A magnesium(<sc>i</sc>) complex was employed as a highly efficient precatalyst for the hydroboration of carbonates and esters under mild conditions.
Ethylene vinyl acetate rubber (vinyl (VA) content = 50 wt %) (EVM) and ethylene copolymer (VA < (EVA) are polymers with a very similar chemical structure. In this study, novel thermoplastic vulcanizate (TPV) based on EVM/EVA28 28 blend has been successfully fabricated by dynamic vulcanization due to the selective cross-linking of EVM. The morphologies properties TPVs have investigated. It was found that cross-linked EVM phase EVA28 form perfect cocontinuous structure size about 100 nm. TPV...
Stereogenic 2-(N-carbamoyl)pyrrolidinylcuprates prepared from scalemic (i.e., enantioenriched) N-Boc-2-lithiopyrrolidine and THF soluble CuCN·2LiCl react with vinyl iodides, triflates, β-iodo-α,β-enoates, propargyl mesylates, allyl bromide to afford the substitution products excellent enantioselectivity. Excellent enantiomeric ratios are obtained in conjugate addition reactions methyl ketone while low can be achieved acrylate esters using HMPA/TMSCl activation. Enantiomeric vary substrate...

A fluorescent and robust superhydrophobic coating based on a fluorinated polypyrene/silica hybrid film was prepared readily the large-scale substrates.
Magnesium hydroxide (MH) and an intumescent flame retardant (IFR) have been incorporated into a thermoplastic vulcanizate (TPV) for the purpose to fabricate halogen-free elastomeric materials. Significant synergistic effects of MH IFR observed TPV in terms both properties mechanical performance. The mechanism has investigated. results indicate that small amount accelerates degradation matrix induces shrinkage matrix, leading compact unbroken MgO protective layer. Such layer on surface...
Schematic for preparation of the mesoporous MIPs-ZnO NRs and non-mesoporous NRs.
A simple dual-emission probe based on 3-aminophenylboronic acid functionalized CdTe quantum dots (QDs) and carbon (CQDs) was developed for the on-site naked eye detection of dopamine (DA).
The conjugate adducts obtained via coupling of α-(N-carbamoyl)alkylcuprates with α,β-ynoates, α-allenyl esters, or α,β-enoates enimides undergo N-Boc deprotection and cyclization onto the ester functionality upon treatment PhOH/TMSCl, catecholboron bromide, trimethylsilyl triflate. This two-pot sequence provides synthetic routes to 4-alkylidinepyrrolidine-2-ones, 4-alkylidinepyrrolizidin-2-ones, 4-alkylidineindolizidin-2-ones allenyl esters; pyrrolin-2-ones, tetrahydropyrrolizin-2-ones,...

This compound showed expanded substrate scope recognition amino acids good enantioselective fluorescence responses toward 17 common acids. Two diastereomeric imines were synthesized from condensation (R,R)-4 l- and d-valine, reactions...
A novel C3 symmetric 1,1'-bi-2-naphthol-based Schiff base (R,R,R)-6 has been synthesized which shows highly selective fluorescence enhancement with Zn2+ among 21 metal cations examined. Its sensitivity and selectivity are found to be greater than other related C2 (1) C1 [(R)-9] compounds in the fluorescent recognition of . The mechanistic study reveals that probe can attributed formation a unimolecular multidentate 6-coordinated complex.
α-Aminoalkylcuprates prepared from α-lithio carbamates and CuCN·2LiCl participate in 1,4-addition reactions with α,β-unsaturated esters, thiol imides, nitriles poor to excellent yields depending upon the electron-withdrawing substituent substitution pattern of unsaturated substrate. These reagents also undergo conjugate addition α,β-alkynyl sulfoxides, α,β−β,γ-unsaturated allenyl esters. Excellent stereocontrol is achieved additions α-aminoalkylcuprates while stereoselectivity results...
Fast charge transport and high stability are desirable for high-performance electrolytes. However, the two characters typically conflict with each other in conventional Herein, lyotropic liquid crystals (LLCs) were demonstrated first time as potential ideal ion conductors to supersede traditional electrolytes toward energy devices.

Abstract Developing electrolytes combining solid‐like instinct stability and liquid‐like conducting performance will be satisfactory for efficient durable Li‐ion batteries. Herein lamellar lyotropic liquid crystals (LLCs) demonstrate high‐voltage windows, charge transport, inherent thermal safety as solid‐state in lithium‐ion Lamellar LLCs are simply prepared by nanosegregation of [C 16 Mim][BF 4 ] LiBF /Propylene carbonate (PC) solutions, which induce assembly the liquids dynamic pathways....
