Formula: C9H11Br. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single 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.

Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Research Support, Non-U.S. Gov’t, Journal of the American Chemical Society called Copper(I)-Catalyzed Asymmetric Alkylation of Unsymmetrical Secondary Phosphines, Author is Zhang, Shuai; Xiao, Jun-Zhao; Li, Yan-Bo; Shi, Chang-Yun; Yin, Liang, which mentions a compound: 57825-30-6, SMILESS is CCC1=CC=C(CBr)C=C1, Molecular C9H11Br, Related Products of 57825-30-6.

A Cu(I)-catalyzed asym. alkylation of HPAr1Ar2 with alkyl halides is uncovered, which provides an array of P-stereogenic phosphines in generally high yield and enantioselectivity. The electrophilic alkyl halides enjoy a broad substrate scope, including allyl bromides, propargyl bromide, benzyl bromides, and alkyl iodides. Also, 11 unsym. diarylphosphines (HPAr1Ar2) serve as competent pronucleophiles. The present methodol. is also successfully applied to catalytic asym. double and triple alkylation, and the corresponding products were obtained in moderate diastereo- and excellent enantioselectivities. Some 31P NMR experiments indicate that bulky HPPhMes exhibits weak competitively coordinating ability to the Cu(I)-bisphosphine complex, and thus the presence of stoichiometric HPAr1Ar2 does not affect the enantioselectivity significantly. Therefore, the high enantioselectivity in this reaction is attributed to the high performance of the unique Cu(I)-(R,RP)-TANIAPHOS complex in asym. induction. Finally, one monophosphine and two bisphosphines prepared by the present reaction are employed as efficient chiral ligands to afford three structurally diversified Cu(I) complexes, which demonstrates the synthetic utility of the present methodol.
