Related Products of 1271-48-3, In heterogeneous catalysis, catalysts provide a surface to which reactants bind in a process of adsorption. In homogeneous catalysis, catalysts are in the same phase as the reactants. In a document type is Article, and a compound is mentioned, 1271-48-3, name is 1,1′-Ferrocenedicarboxaldehyde, introducing its new discovery.
[1+1], [1+2], [2+1] or [3+1] acyclic and [1+1] or [2+2] cyclic Schiff bases (LALS), containing ferrocene moieties, have been prepared by reaction of formyl- or 1,1?-diformylferrocene and the appropriate amines. Formyl- and 1,1-diformylferrocene form respectively the acyclic [2+1] LW and [2+2]n LZ compounds by reaction with 1,4-diaminomethylbenzene. Similar compounds (LTLV) have been obtained by condensation of aminomethylferrocene and 2,6-diformylpyridine, 2,6-diformyl-4-chlorophenol and 3-methoxy-2-hydroxybenzaldehyde. By reduction of these compounds with NaBH4 the corresponding ferrocene-amine derivatives (L?) have been synthesized. All these compounds have been characterized by physico-chemical measurements (IR, NMR, Moessbauer spectroscopy and FAB mass spectrometry) and LH, derived by the condensation of ferrocene-aldehyde and 1,5-diamino-3-oxa-pentane, also by an X-ray structural determination. The X-ray analysis of crystals of LH, grown from a diethyl ether solution, shows that two independent molecules are present in the asymmetric unit; these two molecules are chemically equivalent with the ferrocenyl groups in the eclipsed form. The coordination ability of these compounds towards d metal ions as copper(II), nickel(II), platinum(II) and rhodium(III) was investigated; while the Schiff bases (L) may suffer hydrolysis, their reduced analogues (L?) form stable, well-defined complexes of the type M(L?)(Cl)n (n=2, 3). The Moessbauer spectra of the prepared compounds show signals with delta at 0.44 and DeltaEQ 2.30 mm s-1 for the Schiff bases LALS and 0.52 and 2.40 mm s-1 for the reduced analogues and hence may be diagnostic of the presence of Fe-CH=N- or Fe-CH2-NH- groups. The signals with delta at 0.51-0.55 and DeltaEQ at 2.34-2.38 mm s-1 for the Schiff bases LTLV, having Fe-CH2-N=CH groups, resemble those of the reduced analogues.

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. We will look forword to the important role of 1271-48-3, and how the biochemistry of the body works.Related Products of 1271-48-3
