Introducing a new discovery about 1271-48-3, Name is 1,1′-Ferrocenedicarboxaldehyde

The zinc complex [PhP(S)(NMeNH2)2]ZnCl2 (2), cleanly obtained by reaction of the phosphodihydrazide PhP(S)(NMeNH2)2 (1) with ZnCl2, is a good reagent in producing new polymetallic compounds by condensation reaction with aldehydes. The reaction of 2 with terephthalaldehyde (3) in a 2/1 or 1/1 stoichiometry leads selectively to the acyclic zinc compound [C6H4-1,4-(CH=NNMePhP(S)NMeNH2)2][ZnCl2]2 (6) or to the macrocyclic zinc complex [PhP(S)C6H4-1,4-(CH=NNMe)2]2[ZnCl2]2 (7). Reaction of compound 2 with 2 equiv of ferrocenecarbaldehyde affords the zinc-iron phosphodihydrazone complex [PhP(S)(NMeN=CHC5H4FeCp)2]ZnCl2 (8) whose structure has beendetermined by X-ray crystallography. Crystal data: triclinic P1-, with a = 12.798(1) A, b = 14.639(2) A, c = 11.744(2) A, alpha =111.74(1)°, beta = 115.92(1)°, gamma = 68.36(1)°, V = 1780.9 A**3, Z = 2; R = 0.037, Rw = 0.044 for 3345 observations and 448 variable parameters. In this neutral trimetallic complex, the Zn(II) center adopts a pseudotetrahedral geometry. This structure is characterized by a five-membered ring with the Zn(II) bonded to the S atom and to one of the N atoms of the phosphodihydrazone ligand PhP(S)(NMeN=CHC5H4FeCp)2 (9). Variable-temperature NMR investigations of 8 show that 9 can act as a hemilabile ligand toward ZnCl2 through an exchange process between the two hydrazone arms in solution. Electrochemical study ofcomplex 8, when compared to the ferrocenyl ligand 9, shows that ZnCl2 complexation induces a shift of 80 mV toward a more anodic potential. Reaction of 2 with the ferrocene-1,1′-dicarbaldehyde also produces the bisferrocenyl dizinc macrocycle [Fe(C5H4CH=NNMePhP(S)NMeN=CHC5H4)2Fe][ZnCl2]2 (10).

Nitrogen-doped carbon nanotubes (N-CNTs) have been synthesized at 850 C via a CVD deposition technique by use of three ferrocenyl derivative catalysts, i.e. para-CN, -CF3 and -Cl substituted-phenyl rings. The synthesized catalysts have been characterized by NMR, IR, HR-MS and XRD. The XRD analysis of the para-CF3 catalyst indicates that steric factors influence the X-ray structure of 1,1?-ferrocenylphenyldiacrylonitriles. Acetonitrile or pyridine was used as carbon and nitrogen sources to yield mixtures of N-CNTs and carbon spheres (CS). The N-CNTs obtained from the para-CF3 catalysts, in pyridine, have the highest nitrogen-doping level, show a helical morphology and are less thermally stable compared with those synthesized by use of the para-CN and -Cl as catalyst. This suggests that fluorine heteroatoms enhance nitrogen-doping in N-CNTs and formation of helical-N-CNTs (H-N-CNTs). The para-CF3 and para-Cl catalysts in acetonitrile yielded iron-filled N-CNTs, indicating that halogens promote encapsulation of iron into the cavity of N-CNT. The use of acetonitrile, as carbon and nitrogen source, with the para-CN and -Cl as catalysts also yielded a mixture of N-CNTs and carbon nanofibres (CNFs), with less abundance of CNFs in the products obtained using para-Cl catalysts. However, para-CF3 catalyst in acetonitrile gave N-CNTs as the only shaped carbon nanomaterials.

The first organometallic derivatives of tricyclic quinazoline derivatives are prepared by condensation of the active C-3 methylene group of 7H-deoxyvasicinones with ferrocenecarbaldehyde. By following this route the conjugated parent alkaloid and derivatives with nitro, amino, as well as some alkanoylamino groups at C-7 were attached at the ferrocene moiety, thereby significantly extending the pi system. In addition, the parent compound was subjected to the reaction by treatment with ferrocene-1,1?-dicarbaldehyde, giving rise to the double condensation product, which is only the second case of a 1,1?-disubstituted ferrocene derivative with two alkaloid substituents. A number of the compounds obtained were subjected to X-ray crystallographic analyses. In all cases, the substituents adopt a coplanar conformation with the ferrocene cyclopentadienyl ligands. The influence of the substituents at C-7 through the extended conjugated pi system on the iron atom is reflected by results of cyclic voltammetric measurements as well as by DFT calculations. 7H-Deoxyvasicinones are condensed with ferrocenecarbaldehyde and with ferrocene-1,1?-dicarbaldehyde to generate extended pi systems with coplanar conformations of the two moieties. The products are investigated by crystal structure analyses, cyclic voltammetry, and DFT calculations.

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.

A soluble (E)-poly(p-phenylenephosphaalkene) having sterically encumbering ligands has been prepared by a phospha-Wittig reaction. This material exhibits a bathochromic shift with respect to E-PPV and with respect to representative model oligomers. We also report the first fluorescence study of a poly(p-phenylenephosphaalkene) and find that this material exhibits fluorescence, though with modest intensity relative to similarly sized carbon-based analogues.

Exclusively planar chirality is exhibited by the ferrocenes obtained in a highly enantioselective synthesis in which a chiral aminoamide acts as a temporary protecting/directing group. This method was used to obtain an enantiomerically pure tetrasubstituted ferrocene, which was transformed into the first C2-symmetric disubstituted ferrocenophane [Eq. (1)].

The crystal structures of 1, 5a, 5b, and 6 were determined by X-ray diffraction studies. Electrospray ionisation mass spectrometry was used to investigate the binding behaviour of 1 and 6 toward alkali as well as transition metal cations. The dioxane-containing species 1 showed high affinity toward Li+ and Na+, whereas the dithiane derivative 6 bound, as expected, preferentially to Hg2+. The Royal Society of Chemistry 2003.

Reference of 1271-48-3, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In an article, 1271-48-3, molcular formula is C12H10FeO2, belongs to iron-catalyst compound, introducing its new discovery.

1,1?-Ferrocene biscarboxaldehyde (1) has been prepared and the aldehyde groups were subsequently protected with acetal groups to produce 1,1?-bisacetalferrocene (2). A ring-locked ferrocene was synthesised by further derivatisation of the cyclopentadiene rings at the 2,2? positions with phosphine substituents to produce 2,2?-bis-(acetal)-1,1?-diphenylphosphinoferrocene (3), which was subsequently coordinated to either a nickel chloride (5) or nickel bromide (6) metal centre. The ring-locked ferrocene complexes produced 2,5?-bis-(acetal)-1,1?-diphenylphosphinoferrocene substitution patterns. The acetal protecting groups of 2,2?-bis-(acetal)-1,1?-diphenylphosphinoferrocene were removed to produce 1,1?-bis-carboxaldehyde-2,2?-diphenylphosphinoferrocene (4). The Cp rings of 1,1?-bisacetalferrocene were also further derivatised at the 2,2? positions with a silane to produce the ring-locked 1,1?-siloxane-2,5?-bisacetalferrocenophane (7). The acetal protecting groups were removed from this to produce 1,1?-siloxane-2,5?-ferrocenophanecarboxaldehyde (8). For both the phosphine and siloxane electrophiles, the substitution on the Cp rings gives chiral products (obtained as racemic mixtures). Due to the highly regioselective nature of the reaction and diastereoselectivity in the products only C2-symmetric compounds were observed without the presence of meso diastereoisomers. Subsequent ring-locking forced the Cp rings to rotate, leading to 1,1?-ring-locked ferrocenes with 2,5?-arrangement of the acetal groups (i.e. on opposite faces of the ferrocene unit).

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.Reference of 1271-48-3
