N-Substituted 2-aza-[3]-ferrocenophanes were easily synthesized from 1,1?-ferrocenedicarbaldehyde and aliphatic amines in high yields. One of the ferrocenophanes served as a ligand for the copper-catalyzed oxidative coupling of 2-naphthol derivatives to give the products in good yields with up to 92% ee, and it also efficiently catalyzed the asymmetric Michael addition reaction as an organocatalyst.

The reductive deoxygenation of alpha-ferrocenyl aldehydes, ketones, alcohols, and carboxylic acid into the corresponding alkylferrocenes is accomplished solely by borane-dimethyl sulfide (BMS) in the absence of any Lewis acid catalyst. This is the first example of such reactivity of BMS. The present method allows the synthesis of alkylferrocenes including those bearing terminally functionalized pendant chains.

The preparation, electrochemical, electronic, and cation sensing properties of an indole-ferrocene-indole triad, are presented. A salient feature of this new structural motif is that the redox-active organometallic fragment is linked to the indole rings by unsaturated nitrogen functionalities. Triad 4 behaves as a highly selective dual-redox and chromogenic chemosensor molecule for Hg 2+ cations: the oxidation redox peak is anodically shifted (DeltaE1/2 = 210 mV), and the low energy band of the absorption spectrum is red-shifted (Deltalambda = 120 mm), upon complexation with this metal cation. This change in the absorption spectrum is accompanied by a dramatic colour change from orange to green which allows the potential for “naked eye” detection. 1H NMR as well as DFT calculations have been carried out to get information about the molecular sites which are involved in bonding.

Electric Literature of 1271-48-3, Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. 1271-48-3, Name is 1,1′-Ferrocenedicarboxaldehyde, molecular weight is 242.0516. In an Article，once mentioned of 1271-48-3

The potassium bis-dithiocarbamate (bis-dtc) salts of 1,3- bis(benzylaminomethyl)benzene (1,3-Bn-ambdtc), 1,3-bis(iso-butylaminomethyl) benzene (1,3-iBu-ambdtc), 1,4-bis(benzylaminomethyl)benzene (1,4-Bn-ambdtc), and 1,4-bis(iso-butylaminomethyl)benzene (1,4- iBu-ambdtc) were reacted with three different diorganotin dichlorides (R2SnCl2 with R = Me, nBu, and Ph) in 1:1 stoichiometric ratios to give the corresponding diorganotin bis- dithiocarbamates. Additionally, the dimethyltin bis-dithiocarbamate of 1,1?-bis(benzylaminomethyl)ferrocene (1,1?-Bn-amfdtc) was prepared. The resulting complexes have been characterized as far as possible by elemental analysis, FAB+ mass spectrometry, IR and NMR (1H, 13C, and 119Sn) spectroscopy, and single-crystal X-ray diffraction, showing that the tin complexes are dinuclear 24- and 26-membered macrocyclic species of composition [{R2Sn(bis-dtc)}2]. As shown by 119Sn NMR spectroscopy, the tin centers are hexa-coordinated in all cases; however, two different coordination environments are possible, as detected by single-crystal X-ray diffraction. In the dimethyltin derivatives of 1,3-Bn-ambdtc, 1,3-iBu-ambdtc, 1,4-Bn-ambdtc, and 1,1?-Bn-amfdtc and the di-n-butyltin derivative of 1,3- iBu-ambdtc, the metal atoms are embedded in skewed-trapezoidal- bipyramidal coordination polyhedra with asymmetrically coordinating trans-oriented dtc groups. In contrast, in the diphenyltin derivative 1,3- iBu-ambdtc, the metal centers have distorted octahedral coordination with symmetrically coordinating cis-oriented dtc functions. Thus, for the complexes derived from 1,3-Bn/iBu-ambdtc, two different macrocyclic structures were observed. In the dimethyl- and di-n-butyltin derivatives, the bridging bis-dtc ligands adopt U-shaped conformations, while in the case of the diphenyltin derivative, the conformation is L-shaped. Furthermore, two different macrocyclic ring conformations can occurr, which differ in the spatial orientation of the substituents attached to the nitrogen atoms (Bn or iBu). The dimethyltin derivatives of 1,4-Bn-ambdtc and 1,1?-Bn-amfdtc have cavities, in which aromatic rings are accomodated in the solid state.

Future efforts will undeniably focus on the diversification of the new catalytic transformations. We’ll also look at important developments of the role of 1271-48-3, and how the biochemistry of the body works.Electric Literature of 1271-48-3

Grinding of 1,1?-ferrocenedicarboxaldehyde with a 2.2 molar equivalent of an aromatic amine in a solvent-free environment provided excellent yields of 1,1?-ferrocenyldiimines. After mixing the aldehyde and amines, a gum or melt formed which eventually solidified to the product. An analytically pure sample of the product was obtained by cold recrystallization. Grinding of ferrocenecarboxaldehyde and 4-substituted phenylacetonitriles under solvent-free conditions provided good yields of the corresponding ferrocenylacrylonitriles. The yield in this reaction was very low when the substituent group para to the acetonitrile group was electron-donating.

With an objective to understand the nonlinear optical properties of organometallic structures, various aryl and vinyl derivatives of ferrocene were synthesized and their nonlinear optical properties were investigated by using degenerate four-wave mixing.The molecular second hyperpolarizability gamma increases strongly with the length of the conjugated ?-electron system.The results show that effective conjugation is determined predominantly by the length of the aryl-vinyl system; the contribution from the ferrocenyl group is less significant.The d-d resonance of the metal in the ferrocene unit does not appear to make an important contribution to optical nonlinearity.The experimental results on ferrocene are compared with those from a recent theoretical study using semiempirical calculations.Although a qualitative agreement with the theoretical result is found, the experimental value of gamma determined by our method is about 4 times larger.Possible sources of such discrepancies are discussed.

In conclusion, we affirm that quantitative kinetic descriptions of catalytic behavior continue to serve as an indispensable tool.Reference of 1271-48-3. In my other articles, you can also check out more blogs about 1271-48-3

Rigid N-(substituted)-2-aza-[3]-ferrocenophanes L1 and L2 were easily synthesized from 1,1 -dicarboxyaldehydeferrocene and the corresponding amines. Ligands L1 and L2 were characterized by 1H NMR, 13C NMR and single-crystal X-ray crystallography. The coordination abilities of L1 and L2 with metal ions such as Cu2+, Mg2+, Ni2+, Zn2+, Pb2+ and Cd2+ were evaluated by cyclic voltammetry. The electrochemical shift (DeltaE1/2) of 125 mV was observed in the presence of Cu2+ ion, while no significant shift of the Fc/Fc + couple was observed when Mg2+, Ni2+, Zn 2+, Pb2+, Cd2+ metal ions were added to the solution of L1 in the mixture of MeOH and H2O. Moreover, the extent of the anodic shift of redox potentials was approximately equal to that induced by Cu2+ alone when a mixture of Cu2+, Mg2+, Ni2+, Zn2+, Pb2+ and Cd2+ was added to a solution of L1. Ligand L1 was proved to selectively sense Cu2+ in the presence of large, excessive first-row transition and late-transition metal cations. The coordination model was proposed from the results of controlled experiments and quantum calculations.

Six symmetrical ferrocenyl Schiff base materials were synthesized and characterized by UV, 1H NMR, mass spectrometry (MS) and elemental analysis. Their off-resonant third-order nonlinear optical properties were measured using femtosecond laser and degenerate four-wave mixing (DFWM) technique. The third-order nonlinear optical susceptibilities chi(3) were 1.961-6.363 × 10-13 esu. The nonlinear refractive indexes n2 were 3.609-11.716 × 10-12 esu. The second-order hyperpolarizabilities gamma of these molecules were 1.967-6.388 × 10-31 esu. The response time were 45.759-73.079 fs. The results indicate that these materials have potential nonlinear optical applications.
