Synthetic Route of 1271-51-8, The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction. 1271-51-8, Name is Vinylferrocene, molecular weight is 203. belongs to iron-catalyst compound, In an Article，once mentioned of 1271-51-8
A series of ferrocenyl-arene dyads, Fc-C=C-Ar, trans-Fc-CH=CH-Ar, and Fc-CH=CH-CH=CH-Ar (Ar = phenyl, 1-naphthyl, 2-naphthyl, 9-phenanthryl, 9-anthryl, 1-pyrenyl, 3-perylenyl) have been synthesized. Their structures and spectroelectrochemical properties are discussed. The molecular structures of several have been determined by X-ray diffraction and the observed structures compared with global free-energy minimized calculated structures. In the solid state all ethynyl dyads have the aromatic ring orthogonal to the ferrocenyl cyclopentadienyl rings, whereas calculations predict a coplanar orientation. Calculated and observed structures agree for the ethenyl dyads with the rings orthogonal and coplanar for the anthryl and pyrenyl dyads, respectively. In most cases the solid-state structures are stabilized by offset pi-stacking interactions between the polycyclic hydrocarbon rings. The two bands in the electronic spectra of the neutral dyads are due to the individual aryl and ferrocenyl end-groups. Upon oxidation at the [Fc]+/0 couple, the ferrocenyl transition is replaced by LMCT bands at lower energy and a new weak band in the NIR assigned to a Fc+ ?aryl transition; these assignments are supported by resonance Raman spectra, and the energy of the Fc+? aryl transition correlates with the ionization energy of the aryl group. These are therefore electrochromic dyads.
