The title of the article was 《Synthesis, spectroscopic, CO-releasing ability, and anticancer activity studies of [Mn(CO)3(L-L)Br] complexes: Experimental and density functional theory studies》.SDS of cas: 14516-54-2 The author mentioned the following in the article:

Two different series of manganese(I) tricarbonyl complexes containing phosphine-based (1-5) and 4′-substituted 2,2′:6′,2′′-terpyridine-based ligands (6-10) have been synthesized in order to study their CO-releasing ability and to investigate their anticancer activity. All the synthesized complexes (1-10) have been fully characterized using standard spectroscopic and anal. techniques. Further 5, 7, and 9 have also been characterized by single-crystal x-ray diffraction studies. Although both the sets of ligands are π-acceptors, they tend to change the Mn-CO bond strength upon complexation, thus affecting the CO release. Photoactivation of 1-5 and 6-10 has been achieved using 365 nm UV irradiation and low intensity visible light, resp. The MnCO bond strength has been examined using the d. functional theory (DFT) and time-dependent DFT (TD-DFT) calculations In order to find the therapeutic viability of the visible light activated complexes, their cytotoxicity has been investigated both in the dark and under irradiation The MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) assay reveals the potential application of some of the synthesized complexes especially towards the lung cancer cells in the dark condition.

A Mn-catalyzed diastereo- and enantioselective hydrogenation of α-substituted β-ketoamides has been realized for the first time under dynamic kinetic resolution conditions. anti-α-Substituted β-hydroxy amides, which are useful building blocks for the synthesis of bioactive mols. and chiral drugs, were prepared in high yields with excellent selectivity (up to >99% dr and >99% ee) and unprecedentedly high activity (TON up to 10000).

The article conveys some information:

Homogeneously catalyzed reactions often make use of additives and promotors that affect reactivity patterns and improve catalytic performance. While the role of reaction promotors is often discussed in view of their chem. reactivity, we demonstrate that they can be involved in catalysis indirectly. In particular, we demonstrate that promotors can adjust the thermodn. of key transformations in homogeneous hydrogenation catalysis and enable reactions that would be unfavorable otherwise. We identified this phenomenon in a set of well-established and new Mn pincer catalysts that suffer from persistent product inhibition in ester hydrogenation. Although alkoxide base additives do not directly participate in inhibitory transformations, they can affect the equilibrium constants of these processes. Exptl., we confirm that by varying the base promotor concentration one can control catalyst speciation and inflict substantial changes to the standard free energies of the key steps in the catalytic cycle. Despite the fact that the latter are universally assumed to be constant, we demonstrate that reaction thermodn. and catalyst state are subject to external control. These results suggest that reaction promotors can be viewed as an integral component of the reaction medium, on its own capable of improving the catalytic performance and reshaping the seemingly rigid thermodn. landscape of the catalytic transformation.

Theor. electron d. (QTAIM) studies in the gas-phase have shown that the attachment of the BH3 group to the metal atom in complexes [Mn(κ3N,H,H-iPr2bzamBH3)(CO)3] (1) and [Ru(η5-C5Me5)(κ3N,H,H-iPr2bzamBH3)] (2) (HiPr2bzamBH3 = N-trihydridoborane-N,N’-bis(isopropyl) benzamidine) is sym. in the latter but asym. in the former, and involves two B-H-metal interactions that are intermediate between κ1H (Shimoi type) and κ2H,B (agostic type). The herein reported results, coupled to previous ones on related complexes having a similar tripod κ3N,H,H-borane ligand, show that the bonding similarities and differences within each particular M(μ-H)2B moiety are not related to the type of metal atom, nor even to its coordination geometry, but mainly to the mol. symmetry.

The synthesis and biol. evaluation of a series of phenanthroline-based visible-light-activated manganese(I) carbon-monoxide-releasing mols. (PhotoCORMs) against ESKAPE bacteria and bacterial biofilms is reported. Four carbonyl compounds of general formula fac-[Mn(NN)(CO)3(L)] have been synthesized and characterized. Despite being thermally stable in the absence of light, these PhotoCORMs readily release CO upon blue (435-450 nm) LED light irradiation as confirmed by spectrophotometric CO releasing experiments (Mb Assay). The antibacterial activity of the four PhotoCORMs has been investigated against a panel of ESKAPE bacteria. The compoundsI[ bromo 1,10-phenanthroline-5-amine, bromo 1,10-phenanthroline-5,6-dione, azido 1,10-phenanthroline-5,6-dione] were found to be effective antibacterials at low concentrations against multidrug-resistant Klebsiella pneumoniae and Acinetobacter baumannii when photoactivated with blue-light. In addition, the PhotoCORMs I[ bromo 1,10-phenanthroline-5-amine, bromo 1,10-phenanthroline-5,6-dione] were found to inhibit the formation of Klebsiella pneumoniae and Acinetobacter baumannii bacterial biofilms at low concentrations (MIC = 4-8 μg/mL), turning out to be promising candidates to combat antimicrobial resistance. The antibacterial and biofilm inhibitory effect of the PhotoCORMs is plausibly due to the release of CO as well as the formation of phenanthroline photo-byproducts as revealed by spectroscopy and microbiol. experiments In the part of experimental materials, we found many familiar compounds, such as Bromopentacarbonylmanganese(I)(cas: 14516-54-2Quality Control of Bromopentacarbonylmanganese(I))

Recommanded Product: Bromopentacarbonylmanganese(I) And the article was included in Journal of the American Chemical Society in 2020. The article conveys some information:

Electrocatalysis is a promising tool for using CO2 as a feedstock in the chem. industry. However, controlling the selectivity for different CO2 reduction products remains a major challenge. The authors report Mn carbonyl complexes with elaborated bipyridine or phenanthroline ligands that can reduce CO2 to either formic acid, if the ligand structure contains strategically positioned tertiary amines, or CO, if the amine groups are absent in the ligand or are placed far from the metal center. The amine-modified complexes are benchmarked to be among the most active catalysts for reducing CO2 to formic acid, with a maximum turnover frequency of up to 5500 s-1 at an overpotential of 630 mV. The conversion even works at overpotentials ≥300 mV, although through an alternative mechanism. Mechanistically, the formation of a Mn-hydride species aided by in situ protonated amine groups is a key intermediate by cyclic voltammetry, 1H NMR, DFT calculations, and IR spectroelectrochem.

《Manganese-Catalyzed β-Methylation of Alcohols by Methanol》 was written by Schlagbauer, Martin; Kallmeier, Fabian; Irrgang, Torsten; Kempe, Rhett. Electric Literature of C5BrMnO5 And the article was included in Angewandte Chemie, International Edition in 2020. The article conveys some information:

We report an earth-abundant-metal-catalyzed double and single methylation of alcs. A manganese catalyst, which operates at low catalyst loadings and short reaction times, mediates these reactions efficiently. A broad scope of primary and secondary alcs., including purely aliphatic examples, and 1,2-amino alcs. can be methylated. Furthermore, alc. methylation for the synthesis of pharmaceuticals has been demonstrated. The catalyst system tolerates many functional groups, among them hydrogenation-sensitive examples; and up-scaling is easily achieved. Mechanistic investigations are indicative of a borrowing hydrogen or hydrogen auto-transfer mechanism involving a bimetallic K-Mn catalyst. The catalyst accepts hydrogen as a proton and a hydride from alcs. efficiently and reacts with a chalcone via hydride transfer.
