The first metal-free thermal protodeboronation of ortho- and para-phenol boronic acids in DMSO was developed. The protodeboronation was successfully applied to the synthesis of ortho- and meta-functionalized phenols using the boronic acid moiety as a blocking group and a directing group, respectively. Mechanistic studies suggested that this protodeboronation proceeds through the coordination of water to the boron atom followed by sigma-bond metathesis.

Due to serious environmental pollutions, the detection of hazardous and explosive nitro-aromatic compounds using metal-organic frameworks (MOFs) have been a promising research field in the current scenario. Here, we report a new fluorescent MOF, [Zn2(TCPE)(tta)2]·2DMF·4H2O·2Me2NH2 + (HNU-34, H4TCPE = 1,1,2,2-tetra(4-carboxylphenyl)ethylene, 1H-tta = 1H-tetrazole) which possesses a 3D configuration and 1D channels along the c-axis. It can serve as a luminescence sensor for the detection of nitrophenol explosives through different quenching effects, especially for the mononitrophenol and dinitrophenol. The detection limits of 2,6-dinitrophenol and trinitrophenol are 29.45 nM and 36.15 nM, respectively, which are among the high level of the reported MOF sensors, especially for DNP.

In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 20439-47-8, name is (1R,2R)-Cyclohexane-1,2-diamine, introducing its new discovery. COA of Formula: C6H14N2

A family of enantiomerically pure ligands based on the cyclobutenedione structure, and containing either an enantiomerically pure amino alcohol or a diamine as the chiral element, has been synthesized. As first examples of their application, these versatile and modularly constructed ligands have been tested in the transfer hydrogenation of acetophenone and in the reduction using borane of this same substrate.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 20439-47-8 is helpful to your research. category: catalyst-ligand

Chemistry is traditionally divided into organic and inorganic chemistry. COA of Formula: C21H14BrN3. The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 89972-76-9

A set of 4?-substituted 2,2?:6?,2?-terpyridines has been synthesized in a one-pot procedure under environmentally friendly reaction conditions using PEG and aqueous ammonia as solvents. This procedure features a short synthetic route, short reaction times, easy work-up, and good yields in comparison to conventional methods. The crystallographic data reveal the influence of the 4?-aryl substituent on the molecular structure and pi-stacking behavior of the respective terpyridines. Georg Thieme Verlag Stuttgart.

Novel chiral bidentate P,N-containing ligands have been easily synthesized by Schiff-base condensation of o-(diphenylphosphino)benzaldehyde and modified chiral diamine, (R,R)-2-(2,5-dimethyl-pyrrol-1-yl)-cyclohexylamine, further reduction with NaBH4. The chiral ruthenium(II) complex could be successfully prepared from the reaction between chiral bidentate aminophosphine ligand and RuCl2(PPh3)3. The chiral bidentate P,N-containing ligands and ruthenium(II) complex were fully characterized by NMR, IR, HRMS and single-crystal X-ray diffraction studies. In the presence of KOH, the asymmetric transfer hydrogenation (ATH) of various ketones catalyzed by the chiral ruthenium(II) complex proceeded smoothly under mild conditions, affording corresponding chiral secondary alcohols with up to 99% conversion and up to 60% ee. Additive such as NH4I was found to be helpful to promoting the enantioselectivity.
