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.

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.

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.

This chapter summarizes research work showing that electrostatic interactions may have considerable effects on the stability of complexes formed by the cucurbit[n]uril hosts. Focusing primarily on work carried out by the author’s research group with the cucurbit[7]uril (CB[7]) molecular receptor, this review highlights the role played by electrostatic interactions involving the host cavity portals, in which considerable negative charge density accumulates due to the carbonyl oxygens lacing the portal rims. Electrostatics are responsible for diminished binding affinities between CB[7] and a number of anionic guests containing one or more carboxylate groups. These electrostatic interactions can be used effectively to control the average location of CB[7] along axle-type guests having terminal -COOH groups as a function of their state of protonation, leading to switchable pseudorotaxane systems. They can also be utilized to advantage to develop favorable lateral interactions between CB[7] and other molecular receptors, which results in systems showing cooperative self-assembly.
