Safety of Bromopentacarbonylmanganese(I)In 2020 ,《Selective reductive cross-coupling of N-heteroarenes by an unsymmetrical PNP-ligated manganese catalyst》 was published in Journal of Catalysis. The article was written by Tan, Zhenda; Xiong, Biao; Yang, Jian; Ci, Chenggang; Jiang, Huanfeng; Zhang, Min. The article contains the following contents:

Herein, by developing an unprecedented manganese catalyst ligating with an unsym. 2-aminotetrahydronaphthyridyl PNP-ligands e.g., I, a new reductive cross-coupling of indoles II (R = H, 5-MeO, 7-Me, 2,5-di-Me, etc.)/1H-pyrrole, 2,5-dimethyl-1H-pyrrole and N-heteroarenes III (R1 = H, 2,3-di-Me, 4-chlorophenyl, thiophen-2-yl, etc.; X = CH, N) was achieved. Mechanistic investigations show that the catalyst-enabled in situ capture of the partially reduced intermediates by interruption of the second transfer hydrogenation of N-heteroarenes constitutes the key to success for the present reaction. The developed chem. proceeds with good substrate and functional group compatibility, high step and atom efficiency, and excellent chemo and regioselectivity, and is applicable for late-stage modification of pyridine-containing biomedical mols., which has established a new platform allowing the linkage of aromatic systems into functional frameworks, and further development of unsym. PNP organometallic complexes and related catalytic transformations.

In 2022,Liu, Sen; Shen, Can; Jiang, Dongsheng; Qian, Cheng; Yang, Zhongmei; Wang, Jianquan; Ye, Wei published an article in Macromolecular Bioscience. The title of the article was 《Cascade Tumor Therapy Platform for Sensitized Chemotherapy and Penetration Enhanced Photothermal Therapy》.Recommanded Product: Bromopentacarbonylmanganese(I) The author mentioned the following in the article:

As a stand-alone therapy strategy may not be sufficient for effective cancer treatment and a combination of chemotherapy with other therapies is a main trend in cancer treatment. A combination of chemotherapy and photothermal therapy (PTT) is reported here to achieve the goal of cascade multistage cancer treatment. A thermally responsive amphiphilic copolymer is designed and then a CuS nanoparticles (NPs)-based carbon monoxide (CO) photoinduced release system and doxorubicin (Dox) are encapsulated to construct the nanomedicine. The large-sized nanomedicine can accumulate in tumors after long circulation in vivo and will generate heat to act as a photothermal therapeutic agent by near IR (NIR) light. Moreover, synergically release of CO and Dox is achieved and acted as a sensitized chemotherapeutic agent. The combination of PTT and chemotherapy sensitization can effectively eliminate active tumor cells in the periphery of the tumor. CuS NPs are also released after the degradation of nanomedicine and small-sized CuS NPs possess better tumor penetration and achieve penetration-enhanced PTT by further NIR irradiation, thereby effectively eliminating tumor cells inside solid tumors. Hence, cascade multistage cancer treatment of “”combined PTT and chemotherapy sensitization””-“”penetration-enhanced PTT”” is achieved, and tumor cells are comprehensively and effectively eliminated. The results came from multiple reactions, including the reaction of Bromopentacarbonylmanganese(I)(cas: 14516-54-2Recommanded Product: Bromopentacarbonylmanganese(I))

《Hydrogenation of Alkenes Catalyzed by a Non-pincer Mn Complex》 was published in ChemCatChem in 2020. These research results belong to Rahaman, S. M. Wahidur; Pandey, Dilip K.; Rivada-Wheelaghan, Orestes; Dubey, Abhishek; Fayzullin, Robert R.; Khusnutdinova, Julia R.. Product Details of 14516-54-2 The article mentions the following:

Hydrogenation of substituted styrenes and unactivated aliphatic alkenes by mol. hydrogen has been achieved using a Mn catalyst with a non-pincer, picolylphosphine ligand. This is the second reported example of alkene hydrogenation catalyzed by a Mn complex. Mechanistic studies showed that a Mn hydride formed by H2 activation in the presence of a base is the catalytically active species. Based on exptl. and DFT studies, H2 splitting is proposed to occur via a metal-ligand cooperative pathway involving deprotonation of the CH2 arm of the ligand, leading to pyridine dearomatization.

Henke, Wade C.; Kerr, Tyler A.; Sheridan, Thomas R.; Henling, Lawrence M.; Takase, Michael K.; Day, Victor W.; Gray, Harry B.; Blakemore, James D. published their research in Dalton Transactions in 2021. The article was titled 《Synthesis, structural studies, and redox chemistry of bimetallic [Mn(CO)3] and [Re(CO)3] complexes》.SDS of cas: 14516-54-2 The article contains the following contents:

Manganese ([Mn(CO)3]) and rhenium tricarbonyl ([Re(CO)3]) complexes represent a workhorse family of compounds with applications in a variety of fields. Here, the coordination, structural, and electrochem. properties of a family of mono- and bimetallic [Mn(CO)3] and [Re(CO)3] complexes are explored. In particular, a novel heterobimetallic complex featuring both [Mn(CO)3] and [Re(CO)3] units supported by 2,2′-bipyrimidine (bpm) has been synthesized, structurally characterized, and compared to the analogous monomeric and homobimetallic complexes. To enable a comprehensive structural anal. for the series of complexes, authors have carried out new single crystal x-ray diffraction studies of seven compounds: Re(CO)3Cl(bpm), anti-[{Re(CO3)Cl}2(bpm)], Mn(CO)3Br(bpz) (bpz = 2,2′-bipyrazine), Mn(CO)3Br(bpm), syn- and anti-[{Mn(CO3)Br}2(bpm)], and syn-[Mn(CO3)Br(bpm)Re(CO)3Br]. Electrochem. studies reveal that the bimetallic complexes are reduced at much more pos. potentials (ΔE ≥ 380 mV) compared to their monometallic analogs. This redox behavior is consistent with introduction of the second tricarbonyl unit which inductively withdraws electron d. from the bridging, redox-active bpm ligand, resulting in more pos. reduction potentials. [Re(CO3)Cl]2(bpm) was reduced with cobaltocene; the ESR spectrum of the product exhibits an isotropic signal (near g = 2) characteristic of a ligand-centered bpm radical. Their findings highlight the facile synthesis as well as the structural characteristics and unique electrochem. behavior of this family of complexes.

Li, Qianqian; Huo, Suhong; Meng, Lingpeng; Li, Xiaoyan published an article in 2022. The article was titled 《Mechanism and origin of the stereoselectivity of manganese-catalyzed hydrosilylation of alkynes: a DFT study》, and you may find the article in Catalysis Science & Technology.Recommanded Product: Bromopentacarbonylmanganese(I) The information in the text is summarized as follows:

The manganese-catalyzed hydrosilylation reaction provides a powerful platform to synthesize organosilicon compounds due to their rich reserves, low toxicity, and promising novel reactivity. In this work, the detailed mechanisms of the manganese-catalyzed hydrosilylation of alkynes using the mononuclear Mn(CO)5Br and binuclear Mn2(CO)10 have been systematically investigated and compared by DFT calculations The mononuclear Mn(CO)5Br-catalyzed hydrosilylation of alkynes belongs to an organometallic mechanism. The computational results indicate that the proposed organometallic catalytic cycle in the early literature cannot completely explain the exptl. results due to the high energy barrier involved. A novel catalytic mechanism, in which the CO firstly dissociates from Mn(CO)4BrL, provides an explanation to the studied reaction. E-pro is the main product of the mononuclear Mn(CO)5Br-catalyzed hydrosilylation of alkynes. Meanwhile, the Mn2(CO)10-catalyzed cycle occurs via radical mechanism, and Z-pro is obtained due to the steric effect. In both mononuclear Mn(CO)5Br and binuclear Mn2(CO)10-catalyzed cycles, the substituted alkyne addition process is the rate-determining step. Our calculated results provide deep insight into and amend the mechanistic details for the significant manganese-catalyzed hydrosilylation of alkyne, which is expected to be informative for the effective utilization of Mn catalysts and stereoselective control of alkyne functionalization reactions. In addition to this study using Bromopentacarbonylmanganese(I), there are many other studies that have used Bromopentacarbonylmanganese(I)(cas: 14516-54-2Recommanded Product: Bromopentacarbonylmanganese(I)) was used in this study.

Safety of Bromopentacarbonylmanganese(I) The article mentions the following:

By reactions of MnBr(CO)5 with 2,2′-bipyridyl-4,4′-dicarboxylic acid and 2,5-pyridinedicarboxylic acid, resp., authors obtained two new Mn-CORMs, [Mn(CO)3(H2O)(HBPDC)] (1) and [Mn(CO)3(CH3CN)(HPYDC)]·CH3CN (2). Complexes 1 and 2 are stable in the absence of light, but they exhibit good CO release ability upon exposure to UV and visible light (blue and green). The CO releasing rate depends on the wavelength of irradiation light, i.e., UV > blue > green, which may make them act as visible light regulated CORMs. It is noteworthy that complexes 1 and 2 possess high water-solubility TD-DFT studies of complexes 1 and 2 reveal that the metal-to-ligand charge-transfer (MLCT) may be responsible for their CO releasing behaviors triggered by UV and visible light. The cellular viability and anti-inflammatory activities evaluation show that complexes 1 and 2 can inhibit the secretion of NO and TNF-α in LPS-stimulated RAW264.7 macrophages with fine biol. compatibility and without apparent cytotoxicity. Furthermore, during the synthesis of complexes 1 and 2, when the pH of solution is hinger than 7, complexes {[Mn(BPDC)]}n (1A) and [Mn(H2O)2(HPYDC)2] (2A) are obtained. Complex 1A is a new 3D Mn-MOF and complex 2A is a zero-dimensional mononuclear compound, which are all without -CO ligand.
