Electric Literature 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.
The syntheses of ferrocene- and ruthenocene-functionalized tetraazamacrocyclic ligands and their corresponding transition metal complexes are described. Reaction of N,N?-bis(2-aminoethyl)-1,3-propanediamine (2,3,2-tet) with 1,1?-diformylferrocene and 1,1?-diformylruthenocene produces the ligands fcmac and rcmac in 81-85% yield. Examination of their CuII, NiII, CoII, ZnII and Fe II/III complexes by IR, UV/Vis, EPR and Moessbauer spectroscopy as well as by electrochemical studies suggests electronic communication between the two metal centers of each complex. The molecular structure of [Cu II(fcmac)(FBF3)]BF4, determined by X-ray structure analysis, is reported and shows that the distance between the two metals is 4.54 A. Stability constants, determined by potentiometric titration, indicate that the copper(II) complexes are of similar stability as those with unfunctionalized tetraazamacrocyclic ligands (e.g. cyclam = 1,4,8,11-tetraazacyclotetradecane); stability constants of cobalt(II) complexes are about 2 log units smaller, those of nickel(II) and zinc(II) complexes are reduced by more than 10 log units. This selectivity is discussed on the basis of the structural studies. Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005.
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.Electric Literature of 1271-48-3
