Ligand Substitution of RuII?Alkylidenes to Ru(bpy)32+: Sequential Olefin Metathesis/Photoredox Catalysis

Ruthenium(II) alkylidene complexes such as the Grubbs? 1st and 2nd generation catalysts undergo a ligand substitution with 2,2?-bipyridine, which readily leads to the common photoredox catalyst Ru(bpy)32+. The application of this catalyst transformation in sequential olefin metathesis/photoredox catalysis is demonstrated by way of ring-closing metathesis (RCM)/photoredox ATRA reactions.

Preparative and structural studies on the carbonyl cyanides of iron, manganese, and ruthenium: fundamentals relevant to the hydrogenases.

The reaction of cyanide, carbon monoxide, and ferrous derivatives led to the isolation of three products, trans- and cis-[Fe(CN)(4)(CO)(2)](2)(-) and [Fe(CN)(5)(CO)](3)(-), the first two of which were characterized by single-crystal X-ray diffraction. The new compounds show self-consistent IR, (13)C NMR, and mass spectroscopic properties. The reaction of trans-[Fe(CN)(4)(CO)(2)](2)(-) with Et(4)NCN gives [Fe(CN)(5)(CO)](3)(-) via a first-order (dissociative) pathway. The corresponding cyanation of cis-[Fe(CN)(4)(CO)(2)](2)(-), which is a minor product of the Fe(II)/CN(-)/CO reaction, does not proceed at measurable rates. Methylation of [Fe(CN)(5)(CO)](3)(-) gave exclusively cis-[Fe(CN)(4)(CNMe)(CO)](2)(-), demonstrating the enhanced nucleophilicity of CN(-) trans to CN(-) vs. CN(-) trans to CO. Methylation has an electronic effect similar to that of protonation as determined electrochemically. We also characterized [M(CN)(3)(CO)(3)](n)(-) for Ru (n = 1) and Mn (n = 2) derivatives. The Ru complex, which is new, was prepared by cyanation of a [RuCl(2)(CO)(3)](2) solution.

Ground-state properties and excited-state reactivity of 8-quinolate complexes of ruthenium(II)

In an effort to explore new systems with highly reducing excited states, we prepared a series of Ru(II) complexes of the type Ru(L)2quo1 (L = bpy (2,2?-bipyridine), phen (1,10-phenanthroline), dmphen (4,7-dimethyl-l,10-phenanthroline), tmphen (3,4,7,8-tetramethyl-l,10-phenanthroline); quo- = 8-quinolate) and investigated their photophysical and redox properties. The absorption and emission spectra of the Ru(L)2quo+ are significantly red-shifted relative to those of the parent complexes Ru(L)32+, with emission maxima in the 757-783 nm range in water. The Ru(L)2quo+ systems are easily oxidized with E1/2(RuIII/III) values ranging from +0.62 to +0.70 V vs NHE, making the emissive Ru ? phen MLCT (metal-to-ligand charge transfer) excited states (E00 ? 1-95 eV in CH3CN) of the Ru(L)2quo+ complexes significantly better reducing agents than the MLCT states of the parent Ru(L)32+ complexes. Emission lifetimes of 17.0 and 32.2 ns were measured for Ru(phen)2quo+ in water and acetonitrile, respectively, and 11.4 ns for Ru(bpy)2quo+ in water. Transient absorption results are consistent with the formation of reduced methyl viologen upon Ru(phen)2quo+ excitation with visible light in water. The possibility of observing the Marcus inverted region in the forward bimolecular electron transfer reaction from the highly reducing*Ru(phen)2quo+ excited state was explored with neutral electron acceptors with reduction potentials ranging from +0.25 to -1.15 V vs NHE.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 10049-08-8 is helpful to your research., Application of 10049-08-8

The synthesis, structure, and electrochemical properties of Fe(C?CC?N)(dppe)Cp and related compounds

The cyanoacetylide complex Fe(C?CC?N)(dppe)Cp (3) is readily obtained from sequential reaction of Fe(C?CSiMe3)(dppe)Cp with methyllithium and phenyl cyanate. Complex 3 is a good metalloligand, and coordination to the metal fragments [RhCl(CO)2], [Ru(PPh 3)2Cp]+, and [Ru(dppe)Cp*]+ affords the corresponding cyanoaceylide-bridged heterobimetallic complexes. In the case of the 36-electron complexes [Cp(dppe)Fe-C?CC?N-ML n]n+, spectroscopic and structural data are consistent with a degree of charge transfer from the iron centre to the rhodium or ruthenium centre via the C3N bridge, giving rise to a polarized ground state. Electrochemical and spectroelectrochemical methods reveal significant interactions between the metal centres in the oxidized (35 electron) derivatives, [Cp(dppe)Fe-C?CC?N-MLn](n+1)+.

Ruthenium-catalyzed two-component addition to form 1,3-dienes: Optimization, scope, applications, and mechanism

A two component coupling of an allene and an activated olefin to form 1,3-dienes has been developed. The requisite allenes are synthesized either from terminal alkynes by a one carbon homologation using copper(I) iodide, paraformaldehyde, and diisopropylamine, via an ortho ester-Claisen rearrangement from a propargylic alcohol, or via a Wittig type reaction on a ketene generated in situ from an acid chloride. Mono- through tetrasubstituted allenes could be synthesized by these methods. Either cyclopentadienylruthenium(II) cyclooctadiene chloride or cyclopentadienylruthenium(II) trisacetonitrile hexafluorophosphate catalyze the addition reaction. When the former catalyst is employed, an alkyne activator is added to help generate the active catalyst. Through systematic optimization studies, a range of conditions was examined. The optimal conditions consisted of the use of cerium(III) trichloride heptahydrate as a cocatalyst in dimethylformamide as a solvent at 60 C. The reaction was found to be chemoselective, and a wide range of functionality was tolerated, including esters, alcohols, nitriles, and amides. When substituted allenes are used, good selectivity can be obtained with proper substitution. A mechanism involving a ruthenacycle is proposed to account for the selectivity or lack thereof in product formation. With disubstituted allenes, selectivity is obtained when beta-hydrogen elimination is favored from a specific site. In tri- and tetrasubstituted allenes, steric issues concerning the C-C bond forming event appear to be the dominant factor in determining product formation. This process represents a highly atomeconomical synthesis of 1,3-dienes in a controlled fashion. The utility of the 1,3-diene products was demonstrated by their use in Diels-Alder reactions to form a variety of cyclic systems including polycyclic structures. This sequence represents a convergent atom economic method for ring formation by a series of simple additions.

Cross metathesis of methyl oleate (MO) with terminal, internal olefins by ruthenium catalysts: Factors affecting the efficient MO conversion and the selectivity

Cross metathesis (CM) reactions of methyl oleate (MO) with cis-4-octene (OC), cis-stilbene (CS) using RuCl2(PCy3)(IMesH2)(CHPh) [IMesH2 = 1,3-bis(2,4,6-trimethylphenyl)imidazolin-2-ylidene; Cy = cyclohexyl] afforded CM products with high MO conversion and high selectivity under high molar (OC/MO, CS/MO) ratios; CM with cis-1,4-diacetoxy-2-butene also afforded metathesis products with high MO conversion under certain conditions. The efficient CM with allyltrimethylsilane proceeded with high activity, whereas the CM with glycidyl ether, beta-pinene, and vanillylidenacetone proceeded with low MO conversion.
