Ruthenium(ll) complexes incorporating 2-(2?-Pyridyl)pyrimidine-4- carboxylic acid

A new bidentate ligand bearing a single carboxylate functionality, 2-(2?-pyridyl)pyrimidine-4-carboxylic acid (cppH), has been prepared and applied in the synthesis of a series of ruthenium(ll) complexes. Reaction of this new ligand with RuII(bpy)2CI2 led to the unexpected oxidation of the starting material to give [RuIII(bpy) 2CI2]CI ¡¤ H2O and a low yield of [RuII(bpy)2(cppH)](PF6)2 ¡¤ H2O (1) on addition of an aqueous KPF6 solution (bpy = 2,2?-bipyridine and cpp = 4-carboxylate-2?-pyridyl-2-pyrimidine). An X-ray crystal structure determination on crystals of 1a, [Ru II(bpy)2(cpp)](PF6), obtained from slow evaporation of an aqueous solution of 1 revealed that the nitrogen para to the carboxylate group in the cpp- ligand coordinates to the ruthenium(ll) center rather than that ortho to this group. The same complex was prepared via decarbonylation of [RuII(cppH)(CO)2CI2] ¡¤ H2O in the presence of bpy and an excess of trimethylamine-N-oxide (Me3NO), as the decarbonylation agent. The coordination of cppH in the precursor is the same as in the final product. The related complex [RuII(phen)2(cppH)](PF6) 2 ¡¤ 2H2O (2) (phen = 1,10-phenanthroline) was similarly synthesized. [RuII(bpy)(dppz)(cppH)](PF6) 2 ¡¤ CH3CN (3) (dppz = dipyrido[3,2,- a;2?,3-c]phenazine) was also prepared by photochemical decarbonylation of [RuII(bpy)(CO)2CI2] giving [Ru II(bpy)- (CO)CI2]2 followed by bridge splitting with dppz to generate [RuII(bpy)(dppz)(CO)CI](PF6) ¡¤ H2O. This intermediate was then reacted with cppH to produce 3, as a mixture of geometric isomers. In contrast to 1, X-ray crystallography on the major product isolated from this mixture, [RuII(bpy)(dppz) (cpp)](NO3) ¡¤ 10H2O, 3N3 indicated that the nitrogen adjacent to the carboxylate was coordinated to ruthenium(ll). Full characterization of these complexes has been undertaken including the measurement of UV-visible and emission spectra. Electrochemical and spectroelectro-chemical studies in acetonitrile show that these complexes undergo reversible oxidation from RuII to RuIII at potentials of 983 ¡À 3 mV, 1004 ¡À 5 mV, and 1023 ¡À 3 mV versus Fc0/+ (Fc = Ferrocene) for 1, 2, and 3N3, respectively.

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 15746-57-3 is helpful to your research., Synthetic Route of 15746-57-3

Design, synthesis, and biological evaluation of platensimycin analogues with varying degrees of molecular complexity

The molecular design, chemical synthesis, and biological evaluation of two distinct series of platensimycin analogues with varying degrees of complexity are described. The first series of compounds probes the biological importance of the benzoic acid subunit of the molecule, while the second series explores the tetracyclic cage domain. The biological data obtained reveal that, while the substituted benzoic acid domain of platensimycin is a highly conserved structural motif within the active compounds with strict functional group requirements, the cage domain of the molecule can tolerate considerable structural modifications without losing biological action. These findings refine our present understanding of theplatensimycin pharmacophore and establish certain structure-activity re lationships from which the next generation of designed analogues of thisnew antibiotic may emerge.

ATP3 and MTP3: Easily Prepared Stable Perruthenate Salts for Oxidation Applications in Synthesis

The Ley?Griffith tetra-n-propylammonium perruthenate (TPAP) catalyst has been widely deployed by the synthesis community, mainly for the oxidation of alcohols to aldehydes and ketones, but also for a variety of other synthetic transformations (e.g. diol cleavage, isomerizations, imine formation and heterocyclic synthesis). Such popularity has been forged on broad reaction scope, functional group tolerance, mild conditions, and commercial catalyst supply. However, the mild instability of TPAP creates preparation, storage, and reaction reproducibility issues, due to unpreventable slow decomposition. In search of attributes conducive to catalyst longevity an extensive range of novel perruthenate salts were prepared. Subsequent evaluation unearthed a set of readily synthesized, bench stable, phosphonium perruthenates (ATP3 and MTP3) that mirror the reactivity of TPAP, but avoid storage decomposition issues.

Catalytic ester-amide exchange using group (IV) metal alkoxide-activator complexes

A process for preparation of amides from unactivated esters and amines has been developed using a catalytic system comprised of group (IV) metal alkoxides in conjunction with additives including 1-hydroxy-7-azabenzotriazole (HOAt). In general, ester-amide exchange proceeds using a variety of structurally diverse esters and amines without azeotropic reflux to remove the alcohol byproduct. Initial mechanistic studies on the Zr(Ot-Bu)4-HOAt system revealed that the active catalyst is a novel, dimeric zirconium complex as determined by X-ray crystallography.

Intramolecular electronic energy transfer in ruthenium(II) diimine donor/pyrene acceptor complexes linked by a single C-C bond

The photophysical behavior of [(bpy)2Ru(L)]2+ complexes L = 4-(1′-pyrenyl)-2,2′-bipyridine, bpy-pyr; 2-(1′–pyrenyl)-1,10-phenanthroline, phen-pyr; and 2-(2′-naphthyl)-1,10-phenanthroline, phen-nap) was investigated in solutions and frozen matrices. The conformation of the linked pyrene differs in the two complexes: The pyrene moiety is conformationally constrained to be nearly perpendicular to the phenanthroline in the phen-pyr complex while the pyrene in the bpy-pyr complex has much greater flexibility about the C-C bond linking the ligand and the pyrene. The 3MLCT excited state of the Ru(II) diimine complex and the 3 (pi?pi*) state of the pyrenyl substituent are nearly isoenergetic; the 3MLCT state is the lowest energy state in the bpy-pyr complex, and the pyrene 3(pi?pi*) state is lower in energy for the phen-pyr complex. The bpy-pyr complex is unique in that the3MLCT state has a very long lived luminescence (approximately 50 mus in degassed CH3CN). Luminescence decays for both pyrene containing complexes can be fit as double exponentials, indicating that the 3MLCT and 3(pi?pi*) states are not in equilibrium. Analysis of decays obtained at several temperatures reveal that energy transfer is slower than relaxation of the 3MLCT state but more rapid than decay of the pyrene localized3(pi?pi*) state. The results also suggest that electronic coupling between the two states is weak despite the fact that the two chromophores are separated by a single covalent bond.
