Abstract Five new heteroleptic copper(I) complexes ( C1‐5 ) of the type [Cu(dpa)( P,P )]BF 4 based on dipyridylamine (dpa) as N , ligand and commercial diphosphines P ancillary ligands have been synthesised through a simple methodology with high yields. All were thoroughly characterised by spectroscopic spectrometric techniques, well theoretical calculations. These showed Metal to Ligand Charge...
Abstract A new solvent/ligand-controlled switchable C–H arylation of 1-methyl-4-nitro-1H-indazole catalyzed by Pd(OAc)2 was achieved. bidentate ligand in DMA promoted the activation at C7 position, while a phosphine H2O oriented C3 position. The and products were obtained moderate to good yields with high regioselectivity.
Abstract Simple reaction procedure, boiling of an equimolar mixture [Re(Cl)(CO) 3 (dppv)] (dppv— cis -1,2-bis(diphenylphosphino)-ethene), 2-(2-pyridyl)benzimidazole (pbi), and TlClO 4 in o -dichlorobenzene solution, leads to two, chromatographically separable, isomers [Re(CO) 2 (dppv)(pbi)] complex. The obtained species, the yellow-emissive [ OC -6–54] orange-emissive -6–53] isomers, have been ...
The synthesis, characterization, electrochemical and photophysical properties of three novel polypyridine rhenium(I) complexes coordinated to an organoselenide ligand, 4-(phenylseleno)-pyridine (PhSepy), structurally related ligands, fac-[Re(CO)3(NN)(PhSepy)]+ NN = 1,10-phenanthroline (phen), 4,7-diphenyl-1,10-phenanthroline (ph2phen) pyrazino[2,3-f]-1,10-phenanthroline (dpq), are reported. In ...
This work utilizes the anthraquinone (AQ) database to identify potential inhibitors of RIPK1 protein for developing medicines targeting AP-associated necroptosis. Screening necroptosis-related genes that play a crucial role in AP is based on GEO and GSEA databases. An optimum AQ receptor-interacting kinase 1 (RIPK1) inhibition was virtually screened using Discovery Studio 2019 tool, with previo...
Coordination Chemistry. In their Research Article (e202205371), Peter Coburger, Hansjörg Grützmacher et al. report (IPr)2C2P2 as a flexible ligand to iron carbonyl fragments, giving access complexes of the general formula [Fe(CO)x{(IPr)2C2P2}]n+. Redox events involve either metal ion or C2P2 ligand. Graphic design: Dr. Christoph Selg and Luise Coburger.
Abstract Hydrothermal synthesis, crystal structure and properties of a new heterometallic coordination polymer [(VO(terpy)) 4 (MoO ) 2 (Mo 8 O 26 )]·2H ( 1 (terpy = 2,2′;6′,2″-terpyridine) are reported. Compound contains two crystallographically unique vanadium(IV) atoms, bonded to terminal oxido ligand further coordinated terpy ligand. The three N atoms occupy the meridional sites distorted {V...
Abstract An improved chemical process has been developed for the synthesis of (S,S)-DACH-Ph Trost ligand. The amidation 2-diphenylphosphinylbenzoic acid and (S,S)-diaminocyclohexane is promoted by stoichiometric CDI catalytic imidazole hydrochloride. resulting product, ligand, isolated as a white solid in 80% yield with >99% ee simple filtration without column chromatography. current facile ...
The benchmarking of the performance for H2 evolution cobalt diimine-dioxime catalysts is provided based on a comprehensive study their catalytic mechanism. latter follows an ECE'CC pathway with intermediate formation Co(II)-hydride and second protonation possibly at basic site ligand, acting as proton relay. This suggests intramolecular coupling between hydride protonated ligand concentration-i...
