Application 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 a article, 1271-48-3, molcular formula is C12H10FeO2, introducing its new discovery.
Electronic interactions in ferrocene- and ruthenocene-functionalized tetraazamacrcocyclic ligand complexes of FeII/III CoII, NiII, CeII and ZnII
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 proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 1271-48-3 is helpful to your research. Application of 1271-48-3
