Safety of Dichloro(benzene)ruthenium(II) dimer. Knowledge is power! The discovery of a new compound of 37366-09-9 can be both undesirable and beneficial. Unexpected comples compound may bring with it unwanted properities, but intentionally finding one can lead to intentional improvenments of the physiochenical properties of the material.

The abundance and evolving pathogenic behavior of bacterial microorganisms give rise to antibiotic tolerance and resistance which pose a danger to global public health. New therapeutic strategies are needed to keep pace with this growing threat. We propose a novel approach for targeting bacteria by harnessing formate, a cell metabolite found only in particular bacterial species, to activate an antibacterial prodrug and selectively inhibit their growth. This strategy is premised on transfer hydrogenation reaction on a biorthogonal substrate utilizing native formate as the hydride source as a means of uncaging an antibacterial prodrug. Using coordination-directed 3-component assembly to prepare a library of 768 unique Ru?Arene Schiff-base complexes, we identified several candidates that efficiently reduced sulfonyl azide functional group in the presence of formate. This strategy paves the way for a new approach of targeted antibacterial therapy by exploiting unique bacterial metabolites.

Formula: C12H12Cl4Ru2, Why do aromatic interactions matter?In this blog, let’s explore why it’s so important to understand aromatic interactions using 37366-09-9 as examples. 37366-09-9, Name is Dichloro(benzene)ruthenium(II) dimer, molecular formula is C12H12Cl4Ru2. In a Article，once mentioned of 37366-09-9

A series of arene Ru(II) salt complexes of the type [(eta6-arene)RuCl(eta2-dppm)]+[ECl3]- (arene = C6H6, p-cymene, 1,3,5-Me3C6H3; E = Ge, Sn) bearing trichlorogermanate and trichlorostannate anions are reported. Starting from the known complexes: [(eta6-C6H6)RuCl2(eta1-dppm)] (1), [(eta6-p-cymene)RuCl2(eta1-dppm)] (3) and the novel complex [(eta6-1,3,5-Me3C6H3)RuCl2(eta1-dppm)] (7) (dppm = 1,1-bis(diphenylphosphino)methane), reactions with SnCl2 or GeCl2(dioxane) respectively afforded, by halide abstraction at the ruthenium(II) centres in 1, 3 or 7 the salts: [(eta6-C6H6)RuCl(eta2-dppm)]+ SnCl3? (2), [(eta6-p-cymene)RuCl(eta2-dppm)]+ SnCl3? (4), [(eta6-C6H6)RuCl(eta2-dppm)]+ GeCl3? (5), [(eta6-p-cymene)RuCl(eta2-dppm)]+ GeCl3? (6), [(eta6-1,3,5-Me3C6H3)RuCl(eta2-dppm)]+ SnCl3? (8) and [(eta6-1,3,5-Me3C6H3)RuCl(eta2-dppm)]+ GeCl3? (9). The trichlorostannate complexes 2, 4 and 8 are extremely rare examples of ruthenium complexes bearing the SnCl3? counter anion, and the complexes 5, 6 and 9 are the first examples of ruthenium trichlorogermanate complexes to be reported. All compounds were isolated in high yields as air stable materials and were spectroscopically characterized by multinuclear NMR: (1H, 31P{1H}, 13C{1H}), Infra-red (IR), UV?Vis, and high resolution electrospray ionization mass spectrometry (HR-ESI-MS), the latter both in (+) and (?) mode. Additionally, single crystal X-ray diffraction analyses of salts 4 and 6 are reported, revealing pseudotetrahedral Ru(II) centres with eta6 bound p-cymene ligands and eta2-bound dppm ligands with statistical disorder on the ECl3- anions (E = Ge (6), Sn (4)). Density functional theory calculations (B3LYP with the basis set 6-31 + G(d,p) for H, C, P and Cl atoms; while for Ru, Ge, and Sn atoms DGDZVP basis set) are reported for salts 4 and 6 revealing localization of the LUMOs on the ruthenium-arene rings and some localization on the chloride atom. Finally, MTT in vitro cytotoxicity assays for the MCF-7 and MDA-MB-231 breast cancer cell lines are reported for all complexes and compared to cisplatin. All complexes show remarkable in vitro cytotoxic activity and most are considerably more cytotoxic than cisplatin in both breast cancer cell lines: IC50 values range from 2.25 muM (compound 2) to 5.97 muM (compound 9) (cisplatin = 5.74 muM) in MCF-7 cells; 2.20 muM (compound 2) to 6.39 muM (compound 5) (cisplatin = 13.98 muM) in MDA-MB-231. Moreover, when compared to non-malignant breast epithelial cells (MCF12A), all complexes exhibit promising selectivity indices (SI) with compound 5 having the highest SI in MCF-7 cells at 4.8; and compound 6 at 3.65 in MDA-MB-231, with most of the other compounds also being considerably more selective than cisplatin on both cell-lines (SI = 2.26 on MCF-7 and 0.93 on MDA-MB-231). A clonogenic assay was conducted for salts 5 and 6 and the results reveal that both compounds inhibited long-term (14 days) survival in both breast cancer cell lines tested indicating these drugs are very promising candidates for pre-clinical studies.

Reference of 37366-09-9

A full account of half-sandwich complexes of ruthenium(II) having three-legged “piano-stool” geometry supported by tridentate (2-pyridyl)alkylamine ligands is presented. Reaction of the dimer [{(eta6-C6H6)RuCl(mu-Cl)}2] with N-methyl-N,N-bis(2-pyridylmethyl)amine (MeL*) in CH3OH in the presence of NH4PF6 affords the complex [(eta6-C6H6)Ru(MeL*)][PF6]2 (1). A similar reaction with N-methyl-N,N-bis(2-pyridylethyl)amine (MeL**), however, affords a non-organometallic Ru(III)-dimeric complex [(MeL* *)2 Ru2III (mu -O) (mu -Cl) Cl2] [PF6] (5) (the composition of this complex has been established by physicochemical method). Nucleophilic addition reaction on 1 with NaBH4 leads to the isolation of a cyclohexadienyl complex [(eta5-C6H7)Ru(MeL*)][PF6] (3). The molecular structure of 1 · 2CH3CN, 3, and previously reported cyclohexadienyl complex [(eta5-C6H7)Ru(MeL)][PF6] (4) [MeL = N-methyl-[(2-pyridyl)ethyl(2-pyridyl)-methyl]amine], obtained from the reaction between NaBH4 and previously reported “piano-stool” complex [(eta6-C6H6)Ru(MeL)][PF6]2 (2), has been confirmed by X-ray crystallography. Solution-state structure of new complexes 1 and 3 has been elucidated by their 1H NMR spectra in CD3CN. The behavior of complex 3 has been investigated with the aid of two-dimensional 1H NMR spectroscopy, as well. An attempt has been made to provide a rationale for the effect of supporting tridentate N-donor ligand [MeL, MeL*, and MeL**], varying in the chelate ring-size on (i) the relative stability of half-sandwich eta6-benzene Ru(II) complexes and (ii) the electrophilicity of Ru(II)-coordinated benzene ring on the nucleophilic addition reactions.

Methyl vinyl glycolate (methyl 2-hydroxybut-3-enoate, MVG) is available by zeolite catalyzed degradation of mono- and disaccharides and has the potential to become a renewable platform molecule for commercially relevant catalytic transformations. This is further illustrated here by the development of four reactions to afford industrially promising structures. Catalytic homo metathesis of MVG using Grubbs-type catalysts affords the crystalline dimer dimethyl (E)-2,5-dihydroxyhex-3-enedioate in excellent yield and with meso stereochemical configuration. Cross metathesis reactions between MVG and various long-chain terminal olefins give unsaturated alpha-hydroxy fatty acid methyl esters in good yields. [3,3]-Sigmatropic rearrangements of MVG also proceed in good yields to give unsaturated adipic acid derivatives. Finally, rearrangement of the allylic acetate of MVG proceeds in acceptable yield to afford methyl 4-acetoxycrotonate.
