Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: Bromoferrocene, is researched, Molecular C10BrFe, CAS is 1273-73-0, about Proton NMR kinetic studies of hydrogen-deuterium exchange of ferrocene and some monosubstituted derivatives.HPLC of Formula: 1273-73-0.
NMR spectroscopy was used to determine the rates of H exchange in the various positions of ferrocene and some monosubstituted ferrocenes (-Br, -COOH, -CN). The activation parameters were also determined A quant. estimate of the interannular transmission effect is made and suggested to be operating through a primarily inductive mechanism. It is suggested that the exchange involves the preliminary formation of a π-complex between the electrophile and the cyclopentadienyl rings.
When you point to this article, it is believed that you are also very interested in this compound(1273-73-0)HPLC of Formula: 1273-73-0 and due to space limitations, I can only present the most important information.
