Nltroxyl (HNO) demonstrates a unique chemical and biological profile compared to nitric oxide (NO). Phosphorus NMR studies reveal that HNO reacts with triarylphosphines to give the corresponding phosphine oxide and aza-ylide. In the presence of a properly situated electrophilic ester, the aza-ylide undergoes a Staudinger ligation to yield an amide with the nitrogen atom being derived from HNO. These results define new HNO reactivity and provide the basis of new HNO detection methods.

2H-Labelled and 18O-labelled cyclopentenyl esters (±)-4 and (±)-5 are used as probes for memory effects in Pd-catalysed allylic alkylation. 2H-Labelled alkylation product 6 arising from stereospecific Pd-catalysed reaction of (±)-4 was analysed by a novel 13C NMR method involving 2H- isotope shifts and paramagnetic diastereotopic shifts. When catalysts bearing the Trost modular ligand (R,R)-3 were employed, variable memory effects were observed with the slower reacting chirality mismatched (R)-4 substrate- catalyst pairing. The memory effect is dependent on nucleofuge steric bulk and not pK(a). Attack by [L1CH(CO2CH3)2] occurs with reversed site selectivity but (R)-4 remains the mismatched substrate. Mismatched ionisation leading to a Pd-piallyl in which (R,R)-3 acts as a monophosphine ligand may explain the memory effect.

An unprecedented study on the inhibitory activities of a class of phosphane gold(i) complexes on E. coli dihydrofolate reductase (DHFR) is reported. The gold(i) complexes considered in this work consist of azolate or chloride ligands and phosphane as co-ligands. The ligands have been functionalized with polar groups (-COOH, -COO-, NO2, Cl, CN) to obtain better solubility in polar media. Neutral, anionic and cationic gold(i) complexes have been tested as DHFR inhibitors by means of a continuous direct spectrophotometric method. X-ray structural characterizations were performed on ((triphenylphosphine)-gold(i)-(4,5-dicyanoimidazolyl-1H-1yl) and on the analog (triphenylphosphine)-gold(i)-(4,5-dichloroimidazolyl-1H-1yl). The inhibition constants obtained from the enzyme tests range from 20 muM to 63 nM (auranofin) and are conducive to promoting these compounds as potential DHFR inhibitors. This journal is

A novel fluoran-based fluorescent probe 2 has been designed and synthesized by using a strategy of blocking the intramolecular photoinduced electron transfer (PET) process. The probe keeps a ring-closed spirolactone structure in aqueous buffer solution. However, the oxidation of the probe by ClO? perturbs a new equilibrium of the structural interconversion between the nonfluorescent spirolactone and the fluorescent ring-opened zwitterion, which generates a highly selective fluorescent probe for ClO?. Meanwhile, the probe is cell membrane permeable and can be utilized as fluorescent probe for imaging ClO? in living cells.

In recent years, polymerization processes activated by light have attracted a great deal of interest due to the wide range of applications in which this polymerization technique is involved. Parallel to the traditional industrial applications ranging from inks, adhesives, and coatings, the development of high-tech applications such as nanotechnology and 3D-printing have given a revival of interest to this polymerization technique known for decades. To initiate a photochemical polymerization, the key element is the molecule capable to interact with light, i.e., the photoinitiator and more generally the photoinitiating system, as a combination of several components is often required to create the reactive species responsible for the polymerization process. With the aim of reducing the photoinitiator content while optimizing the polymerization yield and/or the polymerization speed, photocatalytic systems have been developed, enabling the photosensitizer to be regenerated during the polymerization process. In this review, an overview of the photocatalytic systems developed for polymerizations carried out under a low light intensity and visible light is provided. Over the years, a wide range of organometallic photocatalysts has been proposed, addressing both the polymerization efficiency and/or the toxicity, as well as environmental issues.

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 17261-28-8, Name is 2-(Diphenylphosphino)benzoic acid, name: 2-(Diphenylphosphino)benzoic acid.

The diphosphine anhydride (PCO)2O was prepared in high yield by DCC coupling of 2-diphenylphosphinobenzoic acid. The diphosphine oxidatively adds to Fe(0) carbonyls to give the acyl carboxylate Fe(PCO)(PCO 2)(CO)2 (1). The complex adopts a distorted octahedral geometry with trans phosphines and cis carbonyl ligands. Treatment of Ni(COD)2 with (PCO)2O afforded the square-planar acyl carboxylate Ni(PCO)(PCO2) (2) with trans phosphine ligands. Upon treatment with PMe3, 1 gives the monocarbonyl Fe(PCO)(PCO 2)(CO)(PMe3), whereas 2 and PMe3 react to give the pentacoordinate adduct 2PMe3. Both 1 and 2 give 1:1 adducts with B(C6F5)3 (BPhF3). Crystallographic analysis revealed that the borane binds to the noncoordinated carboxylate oxygen in both cases. The value of nuCO for the carboxylato ligand decreased by 45 cm-1, and in the case of 1BPh F3, nuCO for the CO ligands increased by 15 cm-1. In solution, 1BPhF3 exists as an equilibrium mixture of three isomers, including a kinetic isomer and another isomer that selectively crystallizes.
