Irreversible inhibitors are therefore the equivalent of poisons in heterogeneous catalysis. Safety of 1,1′-Diacetylferrocene, Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction by binding to a specific portion of an enzyme and thus slowing or preventing a reaction from occurring. In a patent，Which mentioned a new discovery about 1273-94-5

The heat capacities of acetylferrocene, 1,1?-diacetylferrocene, and 1,1?-diethylferrocene were investigated by low-temperature adiabatic calorimetry in the temperature range from 5 to 300 K and their thermodynamic functions were calculated. The enthalpies of combustion of the substances were determined by calorimetry of combustion, and the thermodynamic functions of their formation were calculated by quantum chemistry methods. Inter- and intramolecular interactions of the ferrocene derivatives were also studied by the methods of molecular mechanics and molecular dynamics.

Synthetic Route of 1273-94-5, Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. 1273-94-5, Name is 1,1′-Diacetylferrocene, molecular weight is 262.0412. In an Article，once mentioned of 1273-94-5

Treatment of the a-dimethylamino[3]ferrocenophane derivative 3 with n-butyllithium results in a directed o-metalation at the adjacent Cp ring of the ferrocene unit to selectively yield the (R*,R*,p-S*) diastereomer 4. Similarly, lithiation of rac-12 gives (R*,p-S*)-13. Both these compounds form mesc-type dimers in the crystal that feature a central C2Li2 four-membered-ring moiety. Compound 13 crystallizes with excess n-butyllithium to form a (13-n-BuLi) dimer that was also characterized by X-ray diffraction. Directed lithiation of the nonbridged ferrocene derivative l-(dimethylaminobenzyl)ferrocene (16) with tertbutyllithium resulted in an opposite stereoselectivity to yield (R*,p-R*)-17, which forms a chiral dimeric structure in the solid state, as was revealed by its X-ray crystal structure analysis.

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. Recommanded Product: 1293-65-8. In heterogeneous catalysis, catalysts provide a surface to which reactants bind in a process of adsorption. Introducing a new discovery about 1293-65-8, Name is 1,1′-Dibromoferrocene

We report the synthesis and full characterization of the entire haloferrocene (FcX) and 1,1?-dihaloferrocene (fcX2) series (X = I, Br, Cl, F; Fc = ferrocenyl, fc = ferrocene-1,1?-diyl). Finalization of this simple, yet intriguing set of compounds has been delayed by synthetic challenges associated with the incorporation of fluorine substituents. Successful preparation of fluoroferrocene (FcF) and 1,1?-difluoroferrocene (fcF2) were ultimately achieved using reactions between the appropriate lithiated ferrocene species and N-fluorobenzenesulfonimide (NFSI). The crude reaction products, in addition to those resulting from analogous preparations of chloroferrocene (FcCl) and 1,1?-dichloroferrocene (fcCl2), were utilized as model systems to probe the limits of a previously reported “oxidative purification” methodology. From this investigation and careful solution voltammetry studies, we find that the fluorinated derivatives exhibit the lowest redox potentials of each of the FcX and fcX2 series. This counterintuitive result is discussed with reference to the spectroscopic, structural, and first-principles calculations of these and related materials.

Dehydrogenation of alcohols by three iridium pincer complexes, IrH(Cl)[2,6-(tBu2PO)2C6H 3] (1), {IrH(acetone)[2,6-(tBu2PO) 2C6H3]}{BF4} (2), and IrH(Cl)[{2,5-(tBu2PCH2)2C 5H2}Ru(C5H5)] (3), is reported, in both the presence and the absence of a sacrificial hydrogen acceptor. Dehydrogenation of secondary alcohols proceeds in a catalytic mode with turnover numbers up to 3420 (85% conversion) for acceptorless dehydrogenation of 1-phenylethanol. Primary alcohols are readily decarbonylated even at room temperature to give catalytically inactive 16e Ir-CO adducts. The mechanism of this transformation was studied in detail, especially for EtOH; new intermediates were isolated and characterized.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, Recommanded Product: 1271-48-3, In homogeneous catalysis, catalysts are in the same phase as the reactants. In a article, mentioned the application of 1271-48-3, Name is 1,1′-Ferrocenedicarboxaldehyde, molecular formula is C12H10FeO2

New open-chain tetraamines containing ferrocene, 1,1?-bis(5-methyl-2,5-diazahexyl)ferrocene L1 and 1,1?-bis(2,5-diazahexyl)ferrocene L2, have been synthesized and characterized. Their protonation behaviour has been studied by potentiometric titrations in water (0.1 mol dm-3 KNO3, 25C). The co-ordination ability of L1 towards the divalent metal ions Ni2+, Cu2+, Zn2+, Cd2+ and Pb2+ has also been studied. It forms both mono-and bi-nuclear complexes with Ni2+, Cu2+, Zn2+ and Cd2+ whereas only mononuclear species were found for Pb2+. The electrochemical behaviour of L1 has been studied in CH2Cl2 and water, E1/2 is pH-dependent and from the E1/2 vs. pH curve the protonation constants of oxidized L1 (FeIII) were determined. Similar electrochemical experiments were carried out for L1-H+-M2+ systems. The good agreement between the E1/2 vs. pH and z vs. pH curves (z = average charge calculated from potentiometric data) appears to suggest that the ferrocene-substrate interaction is mainly electrostatic.

Reaction of [IrCp?Cl2]2 with ferrocenylimines (Fc=NAr, Ar=Ph, p-MeOC6H4) results in ferrocene C-H activation and the diastereoselective synthesis of half-sandwich iridacycles of relative configuration Sp?,RIr?. Extension to (S)-2-ferrocenyl-4-(1-methylethyl)oxazoline gave highly diastereoselective control over the new elements of planar chirality and metal-based pseudo-tetrahedral chirality, to give both neutral and cationic half-sandwich iridacycles of absolute configuration Sc,Sp,RIr. Substitution reactions proceed with retention of configuration, with the planar chirality controlling the metal-centred chirality through an iron-iridium interaction in the coordinatively unsaturated cationic intermediate.
