The reactivity of NbCl5, NbF5 and TaCl5 with a selection of commercial imines was investigated for the first time by using dichloromethane as reaction medium. NbCl5 reacted with Ph2CNH, in 1:2 molar ratio, affording [Ph2CNH2][NbCl5(NCPh2)], 1, in 55% yield, as result of imine self-protonation. T...

The antitumor, antibacterial and antioxidant activity, DNA interaction and cathepsin B inhibition of cyclo-ortho-palladated and -platinated compounds [Pd(C,N)]2(μ-X)2 [X = OAc (1), X = Cl (2)] and trans-N,P-[M(C,N)X(PPh3)] [M = Pd, X = OAc (3), M = Pd, X = Cl (4), M = Pt, X = Cl (5)] are discus...

Treatment of benzophenone imine with the stoichiometric amount of Pd(OAc)2 in acetic acid at 60 °C produced the corresponding acetato-bridged five-membered ortho-cyclopalladated dimer [Pd{C6H4CPhNH}(μ-OAc)]2 (1), which was isolated in pure form in a 79% yield. Reaction of 1 with an excess of L...

A novel carbon paste ion selective electrode which was based on a newly synthesized N,N′-bis(benzophenone imine)formamidine (b-BPEF) as an ionophore was prepared for the determination of silver ion. (b-BPEF) was characterized by elemental analysis, FT-IR, 1H NMR, 13C NMR spectroscopy and X-ray ...

Benzophenone imine [M(η1-NHCPh2)(CO)nP5-n]BPh4 [M = Mn, Re; n = 2, 3; P = P(OEt)3, PPh(OEt)2, PPh2OEt, PPh3] complexes were prepared by allowing triflate M(κ1-OTf)(CO)nP5-n compounds to react with an excess of the imine. Hydride-imine [MH(η1-NHCPh2)P4]BPh4 (M = Ru, Os), triflate-imine [Os(κ1...

A series of hydroxamic acids, involving aliphatic, aromatic and cyclic substrates, were transformed to the corresponding carboxylic acids through NaIO4-mediated oxidative cleavage in mild conditions. Esterification of these acids with TMSCHN2 could result in formation of the corresponding methyl...

Aromatic nitro compounds are extensively used in synthetic chemistry. We disclose a new approach to obtain nitroarenes regioselectively starting from carboxylic acids under acid-free reaction conditions.

Isoflavones are widely consumed by people around the world in the form of soy products, dietary supplements and drugs. Many isoflavones or related crude extracts have been reported to exert pain-relief activities, but the mechanism remains unclear. Voltage-gated sodium channels (VGSCs) play impo...

Due to the high discharge voltage and a favorable theoretical capacity, Na2FePO4F have been attracted much attention as the viable cathode materials for sodium-ion storage. However, the low intrinsic electronic conductivity of Na2FePO4F suppresses its practical applications. Herein, ion doping s...

NBS or NIS mediated direct SN bond formation between azoles and sodium sulfinates is described. The reaction shows good substrate scope and tolerates a wide range of functionalities in both azoles and sodium sulfinate substrates. Pyrazoles are also suitable for this method, various 4-halopyrazol...

Twelve asparagus accessions collected from natural regions of Iran were analyzed by flow cytometry to assess their ploidy level. These accessions belong to both cultivated and wild species (A. officinalis, A. persicus, A. breslerianus, A. verticillatus) from the Asparagus subgenus (x = 10). Diff...

Electrospinning is used to fabricate sodium ion conducting fiber membranes composed of polyethylene oxide (PEO), sodium tetrafluoroborate (NaBF4), and succinonitrile (SN) as plasticizer.As compared to conventionally prepared lithium electrolyte membranes with identical composition (PEO:SN:LiBF4)...

Sodium ion battery attracts significant attentions due to its unlimited sodium resources and low cost. However, sodium ion battery usually suffers from the cathode materials' low capacity and poor cyclic stability. Here we demonstrate that the ultrafine Cu7S4 nanoparticles as cathode for so...

In the present study, we have designed and synthesized a series of 1-benzyl-2-methyl-3-indolylmethylene barbituric acid analogs (7a–7h) and 1-benzyl-2-methyl-3-indolylmethylene thiobarbituric acid analogs (7i–7l) as nucleophosmin 1 (NPM1) inhibitors and have evaluated them for their anti-cance...
