Synthetic Route of 37366-09-9. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 37366-09-9, Name is Dichloro(benzene)ruthenium(II) dimer. In a document type is Article, introducing its new discovery.

Visible light driven water splitting in a dye-sensitized photoelectrochemical cell (DSPEC) based on a phosphonic acid-derivatized donor-pi-acceptor (D-pi-A) organic dye (P-A-pi-D) is described with the dye anchored to an FTO|SnO2/TiO2 core/shell photoanode in a pH 7 phosphate buffer solution. Transient absorption measurements on FTO|TiO2|-[P-A-pi-D] compared to core/shell, FTO|SnO2/TiO2(3 nm)|-[P-A-pi-D], reveal that excitation of the dye is rapid and efficient with a decrease in back electron rate by a factor of ?10 on the core/shell. Upon visible, 1 sun excitation (100 mW cm-2) of FTO|SnO2/TiO2(3 nm)|-[P-A-pi-D] in a phosphate buffer at pH 7 with 20 mM added hydroquinone (H2Q), photocurrents of ?2.5 mA cm-2 are observed which are sustained over >15 min photolysis periods with a current enhancement of ?30-fold compared to FTO|TiO2|-[P-A-pi-D] due to the core/shell effect. On surfaces co-loaded with both -[P-A-pi-D] and the known water oxidation catalyst, Ru(bda)(pyP)2 (pyP = pyridin-4-methyl phosphonic acid), maximum photocurrent levels of 1.4 mA cm-2 were observed which decreased over an 10 min interval to 0.1 mA cm-2. O2 was measured by use of a two-electrode, collector-generator sandwich cell and was produced in low faradaic efficiencies with the majority of the oxidative photocurrent due to oxidative decomposition of the dye.

Commercially available catalysts (SIMes)(PCy3)Cl 2Ru(CHPh) (2) and (SIMes)Cl2Ru(CH-o-O-i-PrC 6H4) (3) (SIMes = 1,3-dimesitylimidazolin-2-ylidene) were found to display reversible Ru oxidations via a series of electrochemical measurements. The redox processes enabled the catalysts to be switched between two different states of activity in ring opening metathesis polymerizations and ring closing metathesis reactions, primarily through changes in catalyst solubility. Moreover, treating a solution of 2 dissolved in C6H 6/CH2Cl2/[1-butyl-3-methylimidazolium][PF 6] (6:1:1.1 v/v/v) with 2,3-dichloro-5,6-dicyano-1,4-benzoquinone was found to remove >99.9% of the catalyst, as determined by UV/vis spectroscopy. The methodology described herein establishes a new approach for controlling the activities displayed by commercially available olefin metathesis catalysts and for removing residual Ru species using redox-driven processes.

With the objective of investigating the influence of structural modifications of the polyketide chain of the bengamides upon their antitumoral activities, we targeted the preparation of bengamide E analogues with modification of the stereochemistry at C-2 and at C-3, the substituent at the C-2 position, and the presence of oxirane rings. For the synthesis of these analogues, a new synthetic method for asymmetric epoxidation, developed in our laboratories, was employed utilizing the chiral sulfonium salts 22 and 23. In order to access 2-epi-bengamide E from these epoxy amides, a synthetic methodology, developed by Miyashita, allowed an oxirane-ring-opening reaction with a double inversion of the configuration. Alternatively, an aldol reaction provided access to the same analogue in a shorter and more efficient manner. Finally, biological evaluation of all of these bengamide E analogues demonstrated that the polyketide chain is essential for the antitumor activity of these natural products, not being amenable to structural or configurational modifications.

The catalytic properties of transition metals on various supports in the gas phase hydrogenation reaction of acetonitrile have been studied at atmospheric pressure. The specific catalytic activity with respect to the total process is determined mainly by the chemical nature of M and decreases as the energies of the M-nitrile and M-H bonds increase. The selectivity with respect to primary amine decreases as the surface acidity of the catalyst increases, while the selectivity increases for secondary amine and reaches a maximum for tertiary amine.

Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn’t involve a screen. 246047-72-3, C46H65Cl2N2PRu. A document type is Article, introducing its new discovery.

A general method for carbocyclization of carbohydrates is described using two consecutive organometallic transformations: a novel zinc-mediated domino reaction to give functionalized dienes followed by ring-closing olefin metathesis. In the first reaction, methyl omega-deoxy-omega-iodo glycosides undergo reductive elimination with zinc to produce a terminal double bond. This also liberates the aldehyde which is immediately alkylated in situ by various organozinc reagents. The alkylation occurs under Barbier conditions with methylene iodide and several allyl bromides. Zinc plays a dual role by both promoting the reductive elimination and activating the alkyl halide. Vinylation is carried out by adding divinylzinc. When a new stereogenic center is generated, moderate to excellent stereocontrol is generally observed. An amino group can be introduced by trapping the intermediate aldehyde as an imine prior to the alkylation. The reductive elimination-allylation sequence can also be promoted by indium metal. All the alkylations produce a second double bond, and the obtained dienes are subsequently subjected to ring-closing olefin metathesis to produce the corresponding carbocycles. Newly developed catalyst 30 with an N-heterocyclic carbene ligand is more reactive toward these carbohydrate-derived dienes than commercially available catalyst 18. Acetylation of the free hydroxy groups improves the metathesis reaction significantly. Both five- and six-membered carbocycles are available by this route, including a number of conduritols and quercitols.
