Formate salts are important chemicals widely used in everyday products. The current industrial-scale manufacture of formates requires CO at high pressure and harsh reaction conditions. Herein, we describe a new process for these products without the utilization of hazardous gases and chemicals. By application of ruthenium pincer complexes, a simultaneous methanol dehydrogenation and bicarbonate hydrogenation reaction proceeds, which provides a green synthesis of formate salts with excellent TON (>18 000), TOF (>1300 h-1), and yield (>90 %). Get rid of CO and H 2: An efficient route for the industrial synthesis of formate salts without the utilization of carbon monoxide is highly desirable. A catalytic reaction combining methanol dehydrogenation and bicarbonate hydrogenation has been developed, which provides a green and cost-efficient process for the synthesis of formate salts with excellent turnover numbers and yields.

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 37366-09-9 is helpful to your research., Related Products of 37366-09-9

New benzoyl- and naphthoyl-substituted phosphines have been synthesized, which are stable to air and moisture. Testing these so-called phosphomide ligands in the presence of different ruthenium precursors, the hydrogenation of sodium bicarbonate (NaHCO3) to sodium formate (NaHCO2) proceeded with good catalyst turnover numbers in the range of 1300-1600 at 80 C and a total pressure of hydrogen of 60 bar in the absence of amines or other additives. Similarly, catalytic hydrogenations of carbon dioxide, cinnam-, and benzaldehyde were possible with these new ruthenium complexes. As an intermediate of the catalytic cycle the defined ruthenium complex [(eta6-C6H6)-RuCl2(Cy 2P(1-naphthoyl)] (Cy=cyclohexyl) was prepared and characterized by X-ray crystallography. Ruthenium and phosphor work wonders: Air-stable ruthenium phosphomide complexes are active catalysts in the hydrogenation of sodium bicarbonate, carbon dioxide, and carbonyl compounds. Hydrogenation proceeds with high catalyst turnover numbers in the absence of amines or other additives. The application range of these new ruthenium catalysts also includes the hydrogenation of cinnamaldehyde and benzaldehyde. Copyright

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Product Details of 37366-09-9, you can also check out more blogs about37366-09-9

(4S)-4-Isopropyl-2-(3-nitrophenyl)-4,5-dihydrooxazole ((S)-Phox) is introduced as a novel chiral auxiliary for the asymmetric synthesis of ruthenium polypyridyl complexes. A simply accessible (S)-Phox-bearing precursor serves as the starting point for diastereoselective coordination chemistry: The stereogenic carbon atom of the cyclometalating auxiliary controls the spatial arrangement of incoming 1,10-phenanthrolines during ligand substitution reactions (ratio Lambda:Delta up to 14:1), and further precipitation affords diastereopure compounds. In the following key step, the labilization of the auxiliary ligand is achieved by reduction, thus permitting its replacement against a third polypyridyl ligand with complete retention of the configuration at the metal center (er > 99:1) under mildly acidic conditions, in contrast with previously developed systems that require strong acid. On the basis of results of NMR experiments and X-ray analysis obtained for intermediate compounds, mechanistic considerations for the formation of diastereomeric complexes were made, revealing a Delta ? Lambda isomerization as the reason for the observed limitations in selectivity optimization. This work expands the pool of methods available for the asymmetric synthesis of tris-heteroleptic ruthenium polypyridyl complexes and additionally may serve as an inspiration for the synthesis of other nonracemic octahedral chiral-at-metal compounds.

Treatment of 4-(2?-pyridyl)dibenzothiophene (PyDBT) with the ruthenium carbonyl cluster [Ru3(CO)12] gave the diruthenium(II) complex [Ru(mu-PyBPT-kappa3TV, CS)(CO) 2]2 (1), where PyBPT denotes a dianion of 3?-(2?-pyridyl)-1,1?-biphenyl-2-thiol. The tridentate-N,C,S PyBPT ligand provides a pincer structure consisting of a six-membered thiaruthenacycle and a five-membered azaruthenacycle. The thiolatecontaining NCS pincer ligand in 1 is produced by cleavage of a carbon-sulfur bond adjacent to a pyridyl group in PyDBT. The corresponding reactions using 4-(4?-methyl- 2?-pyridyl)dibenzothiophene (4-MePyDBT) and 4-(6?-methyl-2?- pyridyl)dibenzothiophene (6-MePyDBT) afforded the diruthenium(II) complexes with the same pincer framework [Ru(mu-4-MePyBPT-kappa3N, C, S)(CO)2]2 (2) and [Ru(mu-6-MePyBPT-k3N, C, S)(CO)2J2 (3), respectively. The much slower formation of 3 certifies the reaction path through the initial coordination of the pyridyl group to Ru or the formation of an N,S-chelate structure. Indeed, PyDBT showed the chelating ability in the ruthenium(II) complex [Ru(eta6-C 6H6)(PyDBT-kappa2N,S)Cl]CF3SO 3 (4). Complex 1 contains Ci and C2 symmetrical isomers, 1a and 1b, respectively, which were separated. The latter isomerized to la in DMSO-d6 at 80 C. The stepwise formation of the same NCS pincer ligand was established in the reaction of [Rh(mu-Cl)(CO) 2]2 with PyDBT. The facile reaction at room temperature produced the mononuclear rhodium(I) complex cis-[RhCl(CO)2(eta 1 -N-PyDBT)] (5). The isolated complex 5 was converted to the tetranuclear rhodium(I/III/III/I) complex [ {Rh(mu-PyBPT-kappa3N, C,5)}(-Cl)2{Rh(CO)2}]2 (6) at 100 C for 3 days.

Abstract Novel ruthenium complexes Ru(L)(bpy)2(PF6)2 and platinum organometallic complexes Pt(L)(-?-C6H5CH3)2 with bis-(pyridinyl)ethynyl-phenanthrolines (L = 3,8-bis[2-(3-pyridinyl)ethynyl]-1,10-phenanthroline or 3,8-bis[2-(4-pyridinyl)ethynyl]-1,10-phenanthroline) that function as metalloligands by extra pyridyl units have been prepared using respective synthetic methods. These complexes have broad absorption bands assignable to the MLCT band as the main contributing factor in the 400 to 550 nm wavelength region. Furthermore, these complexes show phosphorescence centered around 680 nm upon excitation at 425 nm. These emissions were assigned to a triplet MLCT-based luminescence for the ruthenium complexes, while a triplet MLCT as the main element, including the interligand charge transfer as the minor element, was assigned for the platinum organometallic complexes. The quantum yields of the emission of the present ruthenium complexes were relatively high, and these complexes are exactly phosphorescent dyes, although the emission intensities of the platinum complexes are poor. These two types of complexes are capable of selective photophysical detection of some metal ions and can serve as metalloligands in the construction of supramolecular metallocycles.

Thioredoxin reductase (TrxR), a major component of the thioredoxin system, makes a critical role in regulating cellular redox signaling and is found to be overexpressed in many human cancer cells. TrxR has become an attractive target for anticancer agents. In this work, three Ru(II) complexes with salicylate as ligand, [Ru(phen)2(SA)] (phen = 1,10-phenanthroline, SA = salicylate, 1), [Ru(dmb)2(SA)] (dmb = 4,4?-dimethyl-2,2?-bipyridine, 2) and [Ru(bpy)2(SA)] (bpy = 2,2?-bipyridine, 3), were synthesized and characterized. The anticancer effect exerted by them was evaluated. Complex 1 was found to exhibit obvious anticancer activity, in comparison with cisplatin, against cancer cell lines, while displaying low toxicity to the normal cell line BEAS-2B. The mechanism of complex 1 cancer cell growth suppress was investigated in A549 cells. Complex 1 exerted its anticancer through inducing apoptosis and triggering cell cycle arrest at the G0/G1 phase. Complex 1 can selectively inhibit TrxR activity and thus promote the generation and accumulation of reactive oxygen species (ROS), which subsequently trigger mitochondrial dysfunction and DNA damage, activate oxidative stress-sensitive mitogen activated protein kinase (MAPK), and suppress the protein kinase B (PKB or AKT) signal pathway, resulting in apoptosis in A549 cells.

A ruthenium trinuclear polyazine complex was synthesized and subsequently immobilized through complexation to a graphene oxide support containing phenanthroline ligands (GO-phen). The developed photocatalyst was used for the photocatalytic reduction of CO2 to methanol, using a 20 watt white cold LED flood light, in a dimethyl formamide-water mixture containing triethylamine as a reductive quencher. After 48 h illumination, the yield of methanol was found to be 3977.57 ± 5.60 mumol gcat -1. The developed photocatalyst exhibited a higher photocatalytic activity than graphene oxide, which provided a yield of 2201.40 ± 8.76 mumol gcat-1. After the reaction, the catalyst was easily recovered and reused for four subsequent runs without a significant loss of catalytic activity and no leaching of the metal/ligand was detected during the reaction.
