  取代基对1-芳基-3-苯基丙烷的NMR化学位移和质量裂解模式的影响

  摘要：

  研究了具有m或p取代基（H，NO 2，Br，Cl，OCH 3，CH 3）的1-芳基-3-苯基丙烷的1 H和13 C化学位移和质谱裂解模式。取代基的电子效应似乎是通过贯穿空间以及通过贯穿键机制传递的，从而导致i- C的化学位移值与Hammettσ值的图呈反相关。质谱显示取代基为给电子体时，取代的苄基片段为基峰，而吸电子取代基为苄基片段。

  3-diphenylpropane. The kinetic pattern of the reaction, conforming to the established scheme of an electrophilic alkylation reaction, is consistent with a rate-determining formation of the σ-complex intermediate, at variance with the tert-butylation of the same series of compounds by Me3C+ ions, occurring at the collisional encounter rate. The kinetic features are explained by a marked effect due to the presence

• The Gas-Phase Reactivity ofp-Me3Si-Substituted 1,3-Diphenylpropane Towards Charged Electrophiles: Intra- and Interannular Hydrogen Migrations

  The gas-phase reaction of pI-Me3SiC6H4(CH2)(3)C6H5 (p-TSDPP) with gaseous cations, including C2H5+, Me2Cl+ and DCO-, has been studied in the pressure range from 10(-8) to 10(3) Torr by Fourier-transform ion cyclotron resonance (FT-ICR) and by the radiolytic technique. The protonated or alkylated intermediates undergo intramolecular migration and intermolecular transfer of protons and/or Me3Si+. The results underline the role of the spectator ring in providing internal solvation to an arenium moiety, as evidenced by the noticeable stability towards Me3Si loss with respect to a single-ring model substrate, p-Me3SiC6H4Me (p-TST), upon reaction with the same gaseous ions. The extent of the alkylation route relative to the alkyldesilylation processes, measured as a function of the arenium ion lifetime, permits derivation of the rate constant for the conversion by proton transfer of the originally formed arenium ions to ipso-silylated isomers (ki). The estimated values of k(i(p-TST))= 5 x 10(9) s(-1) and k(i(p-TSDPP)) = 2 X 10(8) s(-1) at 120 degrees C suggest that intraannular H shifts are faster than ring-to-ring H transfer, in agreement with previous evidence from tert-butylated arenium ions. The reactivity of [Me3Si-arene](+) adducts, adequately described by the Wheland sigma-complex model, does not exclude the intermediacy of an ion-neutral noncovalent complex.
