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 Ring opening of ferrocenyl-substituted cyclopropanes.COA of Formula: C10BrFe.
Treating a mixture of isomeric ferrocenyl-substituted cyclopropanes I (R = Fc throughout this abstract) with excess Ph3CBF4 in CH2Cl2 gave a 2:1 mixture of endo and exo isomers of diferrocenyl-substituted cyclohexene II, formed by cyclodimerization of the initially formed butadiene. Cleavage of 3-methyl-3-ferrocenylcyclopropene with CF3CO2H followed by trapping with excess Me2NPh gave a mixture of E- and Z-4-Me2NC6H4CH2CH:CRMe. A mechanism involving ferrocenyl-stabilized carbocation formation is proposed.
