Reference of 1-(Bromomethyl)-4-ethylbenzene. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: 1-(Bromomethyl)-4-ethylbenzene, is researched, Molecular C9H11Br, CAS is 57825-30-6, about The nucleophilic silyl radical: dual-parameter correlation analysis of the relative rates of bromine-atom abstraction reactions as measured by a rigorous methodology. Author is Jiang, Xi-Kui; Ding, William Fa-Xiang; Zhang, Yu-Huang.
The relative rates [kR(Y)values] of bromine-atom abstraction reactions of 13 p-Y-substituted benzyl bromides (Y = H, Et, tBu, Me3Si, MeS, Ph, F, Cl, Br, CF3, CN, CO2Me, SO2Me) by tris(trimethylsilyl)silyl radicals [(Me3Si)3Si•] in cyclohexane at 80 ° have been measured by a rigorous methodol. Correlation anal. of the kinetic data by the dual-parameter equation (log kY/kH = ρxσ+ρ•σ•) shows that the silyl radical is distinctly nucleophilic and the transition states of the bromine-atom abstraction reactions are affected by both the polar and spin-delocalization effects of the Y-substituents. Comparison of the |ρp/ρJJ•| values suggests that the contribution of the spin-delocalization effects in this Br-atom abstraction reaction may be greater than the spin-delocalization effects in some H-atom abstraction reactions.
