A rapid and diastereoselective synthesis of highly substituted aminobicyclo[4.3.0]nonanes and bicyclo[4.4.0]decanes from alkyne derived allylic alcohols has been developed using a one-pot multi-bond forming tandem catalytic process. Overman rearrangement of the allylic trichloroacetimidates was followed by a ring closing enyne metathesis/cross metathesis sequence of reactions, in which both steps were catalysed by Grubbs second generation catalyst. The resulting exo-diene was then subjected to a hydrogen bonding directed Diels?Alder reaction forming an endo-adduct as a single diastereomer. Variation of the cross metathesis partner and dienophile allowed examination of the scope of this one-pot process and the preparation of a diverse series of highly substituted polycyclic scaffolds.

The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 246047-72-3 is helpful to your research., COA of Formula: C46H65Cl2N2PRu

Abstract: A series of ruthenium, rhodium and iridium complexes with 4-phenyl-1-(pyridin-4yl)methylene thiosemicarbazide (L1) and 4-phenyl-1-(pyridin-4yl)ethylidene thiosemicarbazide (L2) ligands were synthesized and isolated with hexafluorophosphate as a counter ion. All these complexes were fully characterized with the help of FT-IR, UV-Vis, 1H NMR, 13C NMR and elemental analysis. An agar-well diffusion method was employed for evaluation of antibacterial activities against one Gram-positive bacteria Staphylococcus aureus and two Gram-negative bacteria Escherichia coli, Klebsiella pneumoniae. Antimicrobial activity evaluation revealed that Cp* rhodium complexes has a significant antibacterial activity for all the three strains, Cp* iridium and p-cymene ruthenium complexes have shown moderated activity against the microorganisms but none of the complexes surpass the activity of their reference drugs. Results indicated that all the complexes reported here inhibit the growth of bacteria. Graphic Abstract: Synopsis.

Three novel ruthenium(II) complexes, RuX2(IMesH 2)[N,N-diethyl-N?-(2-benzylidene)triazene] [IMesH2 = 1,3-dimesitylimidazolin-2-ylidene; X = Cl- (2), CF 3COO- (3), C6F5COO- (4)] are described. Single-crystal X-ray structure analysis of compounds 2-4 revealed that the triazene ligand exists in the trans form and that the aryl-connected nitrogen atom of the triazene binds to the ruthenium atom to form a five-membered chelate ring. Compounds 2-4 were applied to the UV-induced ring-opening metathesis polymerization (ROMP) of cis-cyclooctene (5) and dicyclopentadiene (6). Whereas all three precatalysts show pronounced thermal latency in the presence of 5 or 6, only compound 2 displays significant photo-ROMP activity. The photoreactivity of precatalysts 2-4, which decreases with increasing electron-withdrawing character and with decreasing pK a of the X groups, is discussed and correlated with the X-ray data of 2-4, with low-temperature 1H NMR measurements as well as with cyclovoltammetric measurements. Three novel complexes, RuX 2(IMesH2)[N,N-diethyl-N?-(2-benzylidene)triazene] [IMesH2 = 1,3-dimesitylimidazolin-2-ylidene; X = Cl- (2), CF3COO- (3), C6F5COO- (4)] are used in the UV-induced ring-opening metathesis polymerization (ROMP) of cis-cyclooctene and dicyclopentadiene. The photoactivity of 2-4 decreases with increasing electron-withdrawing character and with decreasing pKa of the X groups. Copyright

This paper describes the systematic preparation and characterization of new families of triple-decker sandwich complexes incorporating formal cyclo-Et2C2B3H3(4-) bridging ligands, including the first species of this class containing second- or third-row transition metals.Complexes of general formula (L)M(Et2C2B3H3)M'(L) (M = Ru, Os; M’ = Co, Ru; L = cymene , Cp, or C5Me5) were obtained in stepwise fashion via (1) synthesis of closo-(L)M(Et2C2B4H4) metallacarboranes, (2) “decapitation” (apex BH removal) of these complexes to give nido-(L)M(Et2C2B3H5), (3) bridge deprotonation to form the corresponding mono- or dianion, and (4) reaction of the anion with an arene metal halide to generate the desired triple-decker compound.In addition, the cobalt-iron triple-decker CpCo(Et2C2B3H3)FeCp was prepared via treatment of (eta6-C8H10)Fe(Et2C2B3H4)(1-) with Na(1+)Cp(1-) and CoCl2 followed by air oxidation.The reaction of (CO)3RuCl2 with (C5Me5)Co(Et2C2B3H3)(2-) gave the “pseudo-triple-decker” complex (C5Me5)Co(Et2C2B3H3)Ru(CO)3.The triple-deckers, especially those containing osmium, are susceptible to chlorination by RuCl3, OsCl3, or dichloromethane, forming exclusively the 4-chloro derivatives.All of the characterized triple-decker complexes are air-stable crystalline solids (except for the osmium-ruthenium species, which are air sensitive) and have been structurally characterized from their (11)B and (1)H NMR, infrared, visible-UV, and unit- and high-resolution mass spectra, further supported by X-ray crystallographic analyses of (cymene)Ru(Et2C2B3H3)Ru(cymene) (10) and CpCo(Et2C2B3H3)Ru(cymene) (11a).Crystal data for 10: mol wt 561.13; space group PI; Z = 2; a = 10.409(3), b = 11.268(5), c = 12.002(4) Angstroem; alpha = 96.16(3), beta = 99.49(2), gamma = 106.69(3) deg; V = 1312(2) Angstroem3; R = 0.043 for 4777 reflections having F02 > 3?(F02).Crystal data for 11a: mol wt 476.92; space group P21/c; Z = 4; a = 8.808(6), b = 17.708(8), c = 14.194(8) Angstroem; beta = 103.50(4) deg; V = 2153(4) Angstroem3; R = 0.058 for 3289 reflections having F02 > 3?(F02).

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.15746-57-3, Name is Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II), molecular formula is C20H16Cl2N4Ru.

The photophysical properties of a series of ruthenium(II) complexes possessing the dppp2 (dppp2 = pyrido[2′,3′:5,6]pyrazino[2,3-f][1,10] phenanthroline) ligand, [Ru(bpy)n(dppp2)3-n]2+ (bpy = 2,2′-bipyridine; n = 0-3), were investigated. The dppp2-containing complexes possess a remarkable solvent dependence of the luminescence maximum, lifetime, and quantum yield. For example, the emission maximum of [Ru(bpy) 2(dppp2)]2+ blue shifts from 752 nm in CH3CN to 653 nm in CH2Cl2, concomitant with a 19-fold enhancement in the luminescence quantum yield. Electronic structure calculations, transient absorption spectroscopy, and electrochemistry were also used to gain insight into the photophysical properties of the dppp2 complexes. The pronounced solvent effect of the emission of these complexes is attributed to the changes in the relative stabilities of two low-lying metal-to-ligand charge transfer (MLCT) excited states on the environment, where the lowest energy MLCT state is more sensitive to the polarity of the solvent than that which lies at slightly higher energy. Transient absorption spectroscopy shows that the identity of the lowest energy MLCT state does not change as a function of solvent, however, its emission maximum and lifetime are greatly affected by the polarity of the surrounding medium. In contrast to [Ru(bpy)2(dppz)]2+ (dppz = dipyrido[3,2-a:2′,3′-c]phenzine), the lowest energy excited state in the dppp2-containing complexes is assigned as arising from a triplet MLCT state where the charge is localized on the portion of the dppp2 ligand distal to the metal, 3MLCTdis.
