The promoterless AAD (acceptorless alcohol dehydrogenation) reaction mediated by an iridium catalyst Cp*Ir(bpyO) 1-Ir (Cp* = pentamethylcyclopentadienyl, bpyO = alpha,alpha?-bipyridonate) has been theoretically investigated with the density functional theory. The reaction occurs through three steps, including alcohol dehydrogenation, formation of dihydrogen complex, and H2 elimination from the iridium center. In the first two steps, the metal center and the bpyO ligand work cooperatively via the aromatization/dearomatization process of the bpyO ligand. The second step is rate-determining, where the DeltaG0? and DeltaG0 values are 23.9 and 13.9 kcal/mol, respectively. Our calculations demonstrate that the aromatization of the bpyO ligand as well as the charge transfer (CT) from the Cp* ligand to the iridium center plays important roles in stabilizing the transition state of the rate-determining step. We have theoretically and experimentally examined the 4d rhodium analogue Cp*Rh(bpyO) 1-Rh and found that it exhibits similar activity to that of 1-Ir. On the basis of those results, a new catalyst (HMB)Ru(bpyO) 1-Ru (HMB = hexamethylbenzene) is designed both theoretically and experimentally, where a cheaper and more abundant 4d ruthenium element is employed with the HMB and bpyO ligands. Theoretical calculations certainly show that 1-Ru is active for the promoterless AAD reaction via the same reaction mechanism as that of the reaction by 1-Ir. The experiments also demonstrate that 1-Ru is as efficient as 1-Ir for the AAD reaction.

You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.15746-57-3, Name is Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II), molecular formula is C20H16Cl2N4Ru. In a patent, introducing its new discovery.

A highly active supramolecular system for visible light-driven water oxidation was developed with cyclodextrin-modified ruthenium complex as the photosensitizer, phenyl-modified ruthenium complexes as the catalysts, and sodium persulfate as the sacrificial electron acceptor. The catalysts were found to form 1:1 host-guest adducts with the photosensitizer. Stopped-flow measurement revealed the host-guest interaction is essential to facilitate the electron transfer from catalyst to sensitizer. As a result, a remarkable quantum efficiency of 84% was determined under visible light irradiation in neutral aqueous phosphate buffer. This value is nearly 1 order of magnitude higher than that of noninteraction system, indicating that the noncovalent incorporation of sensitizer and catalyst is an appealing approach for efficient conversion of solar energy into fuels.

The reactions of [{(eta6C6H6)RuCl(mu- Cl)}2] and [{(eta6-p-cymene)RuCl(mu,-Cl)}2] with N-[2-(arylchalcogeno)ethyl]morpholines (L) (aryl = Ph/2-pyridyl for S, Ph for Se, 4-MeOC6H4 for Te) and NH4PF6 result in “piano-stool” complexes of RuII of composition [RuCl(eta6-C6H6)/[eta6p-cymene) (L)][PF6], which give characteristic 1H, 13C[{1H}, 77Se[1H), and 125Te[1H] NMR spectra. Some of them have also been characterized by X-ray crystallography [Ru-S, Ru-Se, and Ru-Te bond lengths: 2.3815(12)/2.3742(14), 2.4837(14), and 2.6143(7) A, respectively]. The cyclic voltammograms show that all the complexes undergo irreversible oxidation (E1/2 = 0.290-0.586 V). All the ruthenium complexes have been explored for their catalytic activity in the oxidation of primary and secondary alcohols with N-methylmorpholine N-oxide (NMO), tBuOOH, NaOCl, and NaIO 4 (TON values upto 9.8 ×104). The efficiency of the catalytic oxidation reaction decreases in the order Te > Se > S. The intermediate species involved in the oxidation reactions appear to incorporate the RuIV=O group.

A panel of six new structurally related organometallic arene Ru(II) complexes of general composition [(eta6-benzene)Ru(L)Cl] (1-3) and [(eta6-p-cymene)Ru(L)Cl] (4-6) (L = dimethylaminobenzhydrazones) have been designed and synthesized in search of new ruthenium anticancer drugs. The identities of the synthesized complexes have been well-established by elemental analysis and various spectral (FT-IR, UV-vis, NMR, and HR-MS) methods. The solid-state molecular structures of the ruthenium complexes were determined with the help of X-ray crystallography and confirms the presence of a pseudo-octahedral geometry around ruthenium. Furthermore, cytotoxicity of the complexes has been unveiled with the aid of MTT assay against A549 (lung carcinoma), LoVo (colon adenocarcinoma), HuH-7 (hepato cellular carcinoma) along with the noncancerous 16HBE (human lung bronchial epithelium) cells and compared with the effect of the standard drug cisplatin. Interestingly, complexes 4, 5, and 6 which contain a p-cymene moiety induce a remarkable decrease of cell viability against all the cancer cells tested. The capacity corresponding to the inhibition of A549 cells proliferation was analyzed by 5-ethynyl-2-deoxyuridine (EdU) incorporation assay and indicated a notable effect of p-cymene counterparts 4, 5, and 6 over cisplatin. Further studies such as AO-EB (acridine orange-ethidium bromide) staining, flow cytometry, and Western blot analyses on cell death mechanism signified that the cytotoxicity was associated with apoptosis in cancer cells. This clearly suggests that p-cymene-capped Ru(II) complexes are also one of the propitious cancer therapeutic candidates and are worthy of further investigations.

In this study, a novel photosensitizer having two perylenediimide units and a phenanthroline ruthenium(ii) coordination moiety (Ru-BP) has been developed for photodynamic therapy (PDT) of cancer cells. This new compound was prepared via reactions of two newly designed molecules, namely, 5,6,12,13-tetrakis(4-(tert-butyl)phenoxy)-2-(2,6-diisopropylphenyl)-9-(4-hydroxyphenyl)anthra[2,1,9-def:6,5,10-d?e?f?]diisoquinoline-1,3,8,10(2H,9H)-tetraone (P6) and a bis(2,2?-bipyridyl)-(4,7-dichlorophenanthroline)ruthenium(ii) complex (7). The singlet oxygen production of P6 and Ru-BP was investigated by a chemical method using 1,3-diphenylisobenzofurane as a trap molecule. Additionally, photodynamic therapy efficacy of the novel Ru-BP complex and P6 was evaluated in vitro. Ru-BP significantly decreased the viability of human chronic myeloid leukemia cells under red light but not in the dark, pointing out that the complex, itself, was not cytotoxic and singlet oxygen formation was required for the initiation of cell death mechanisms. Thus, Ru-BP can be effectively used as a photosensitizer in photodynamic therapy, which makes the novel Ru-BP a promising singlet oxygen generator for further biological applications.
