    摘要:
    通过形成两性离子加合物,将合成策略与离子液体 (IL) 和配位相结合,实现了高效的 CO2 吸收。我们策略的本质是利用 Li(+) 和有机碱之间的多齿阳离子配位。还采用了 PEG 功能化的有机碱来增强 CO2 亲和性。ILs 与 CO2 反应形成两性离子加合物。研究了各种锂盐和中性配体之间的配位效应,以及所获得的螯合离子液体的 CO2 容量。例如,PEG150MeBu2N 的 CO2 容量从 0.10 稳步增加到 0.66(每摩尔碱吸收的 mol CO2),这是通过形成由 Li(+) 稳定的两性离子加合物。

  • Synthesis and Characterization of (Disilylanilino)Phosphines

    The disilyl(4-bromo)aniline (Me3Si)(2)NC6H4Br (A) readily undergoes metal-halogen exchange to give the reactive organolithium derivative (Me3Si)(2)NC6H4Li (B). Subsequent reactions with various chlorophosphines, R(R)PCl, or chloro(disilylamino)phosphines, (Me3Si)(2)NP(R)Cl, were used to prepare three varieties of the title compounds: (Me3Si)(2)NC6H4P(R)R (1: R = R = NMe2; 2: R = R = OCH2CF3; 3: R = Ph, R = OCH2CF3; 4: R = R = Ph; 5: R = Ph, R = Me), (Me3Si)(2)NC6H4P(R)N(SiMe3)(2) [6: R = Me; 7: R = i-Pr; 8: R = n-Bu, 9: R = OCH2CF3; 10: R = C6H4N(SiMe3)(2); 11: R = Ph], and (Me3Si)(2)NC6H4P(Ph)R [12: R = n-Bu; 13: R = C6H4N(SiMe3)(2)]. The new compounds 1-13 were generally obtained as colorless, distillable liquids that were fully characterized by NMR (H-1, C-13, and P-31) spectroscopy and elemental analysis.

  • Synthesis and Characterization of Mixed-Substituent P- n -Propyl-N-trimethylsilylphosphoranimines
    作者:John R. Klaehn、Thomas A. Luther、Mason K. Harrup、Frederick F. Stewart
    DOI:10.1080/10426500307867
    日期:2003.7
    One approach to the synthesis of polyphosphazenes is the condensation polymerization of phosphoranimines. In this work, several novel P-n-propyl-N-trimethylsilylphosphoranimines have been synthesized and characterized. Modifications to the literature synthetic routes were required to obtain the precursor phosphines. The N-trimethylsilylphosphoranimines were obtained though oxidation of the phosphine with bromine and then subsequent nucleophilic displacement using lithium phenoxide. These phosphoranimines were stable for long periods of time under dry inert conditions. NMR analyses revealed complex splitting patterns beyond typical coupling due to the stereocenter at phosphorus. We report several approaches to the n-propyl containing phosphines and phosphoranimines.
