    SiCln(NR2)4-n (n = 1, 2, 3, 4) 中 Si–Cl 键的氨解反应已被用于合成二元氨基、氯氨基或混合氨基衍生物,这取决于硅衍生物和胺的性质。反应动力学在一些代表性案例中进行了研究,即 SiCl4 + NHiPr2、SiCl(NMe2)3 + NH2iPr、SiCl2(NEt2)2 + NH2iPr,结果表明速率法则对硅化合物是一阶反应,并且不依赖于胺的浓度。此外,已确定 SiCl2(NEt2)2 与 NH2iPr 的反应的活化参数。SiCl4 和 SiCln(NR2)4-n 之间的配体交换反应生成多种氯氨基衍生物,其组成严格由反应物的摩尔比决定。对于 n = 3(R = Me)和 n = 2(R = Et),研究了 SiCl4 与 SiCln(NR2)4-n 之间的反应动力学。此外,在后者的情况下已确定平衡和活化参数。

  • Preparation, spectroscopic characterization, and deprotonation reactions of Si(NHR)<sub>4</sub> (R = <i>i</i>-Pr, <i>t</i>-Bu, <i>p</i>-tolyl) — EPR identification of persistent radicals formed by oxidation of polyimidosilicates

    日期:2006.1.1

    Treatment of Cl2Si(NH-t-Bu)2 (6a) with t-BuNH2 in boiling toluene yields trisamino(chloro)silane ClSi(NH-t-Bu)3 (7); formation of the tetraaminosilane Si(NH-t-Bu)4 is not observed. The reaction of SiCl4 with 4 equiv. of LiNHR produces the corresponding tetraaminosilanes Si(NHR)4 (2a, R = i-Pr; 2b, R = t-Bu; 2c, R = p-tol) in good yields. When the sterically demanding adamantyl derivative LiHNAd is employed, only disubstitution occurs to form Cl2Si(NHAd)2 (6b). Oxidation of the dimeric imidosilicates Li3[Si(NR)3(NHR)]·THF}2 (3a, R = i-Pr; 3b, R = t-Bu) with 1 mol of iodine produces the persistent radicals Li2[Si(NR)3(NHR)]·LiI·3THF}·, which, on the basis of EPR spectra, exist as SiN3Li3I cubes in solution. The spirocyclic tetraimidosilicate monoanion radical [(THF)2Li(µ-Nnaph)2Si(µ-Nnaph)2Li(THF)2]}–· (10) is formed upon oxidation of the tetralithiated species Li4[Si(Nnaph)4]·4Et2O} (1) and [Li(12-crown-4)]2[(Et2O)2Li(µ-Nnaph)2Si(µ-Nnaph)2Li(Et2O)2]} (8) with iodine. The spectroscopic characterization of hexa(amino)disiloxane (t-BuNH)3SiOSi(NH-t-Bu)3 (14) formed from the reaction of Cl3SiOSiCl3 with 6 equiv. of LiNH-t-Bu is discussed. Key words: imido ligands, silicate, radicals, EPR spectra, lithium.

    在沸腾的甲苯中用t-BuNH2处理Cl2Si(NH-t-Bu)2(6a)可生成三氨基(氯)硅烷ClSi(NH-t-Bu)3(7);未观察到四氨基硅烷Si(NH-t-Bu)4的形成。SiCl4与4当量的LiNHR反应产生相应的四氨基硅烷Si(NHR)4(2a,R = i-Pr;2b,R = t-Bu;2c,R = p-tol)收率较高。当使用立体位阻的莽丁基衍生物LiHNAd时,只发生二取代反应形成Cl2Si(NHAd)2(6b)。氧化双聚合物硝基硅酸锂Li3[Si(NR)3(NHR)]·THF}2(3a,R = i-Pr;3b,R = t-Bu)与1摩尔碘反应产生持久自由基Li2[Si(NR)3(NHR)]·LiI·3THF}·,根据EPR谱,这些自由基在溶液中存在SiN3Li3I立方体形式。在氧化四锂物种Li4[Si(Nnaph)4]·4Et2O}(1)和[Li(12-crown-4)]2[(Et2O)2Li(µ-Nnaph)2Si(µ-Nnaph)2Li(Et2O)2]}(8)与碘反应后形成螺环四硝基硅酸盐单负离子自由基[(THF)2Li(µ-Nnaph)2Si(µ-Nnaph)2Li(THF)2]}–·(10)。讨论了由Cl3SiOSiCl3与6当量LiNH-t-Bu反应形成的六(氨基)二硅氧烷(t-BuNH)3SiOSi(NH-t-Bu)3(14)的光谱表征。关键词:硝基配体,硅酸盐,自由基,EPR谱,锂。

    The aminolysis of the Si–Cl bond in SiCln(NR2)4−n (n = 1, 2, 3, 4) has been employed for the synthesis of binary amido, chloro–amido or mixed amido derivatives, depending on the nature of the silicon derivative and of the amine. The kinetics of the reaction have been investigated in some representative cases, i.e. SiCl4 + NHiPr2, SiCl(NMe2)3 + NH2iPr, SiCl2(NEt2)2 + NH2iPr, showing that the rate law is first-order with respect to the silicon compound and does not depend on the concentration of the amine. Moreover, the activation parameters of the reaction of SiCl2(NEt2)2 with NH2iPr have been determined. The ligand exchange reaction between SiCl4 and SiCln(NR2)4−n yields a number of chloro–amido derivatives, whose composition is strictly determined by the molar ratio of the reactants. The kinetics of the reaction between SiCl4 and SiCln(NR2)4−n were investigated for n = 3, R = Me, and n = 2, R = Et. Moreover in the latter case the equilibrium and activation parameters have been determined.

    γ‐butyrolactam, δ‐valerolactam, ε‐caprolactam, and 1‐isoindolinone (phthalimidine) with up to three methyl moieties were synthesized according to the chemical formula MexSiLac(4–x) (x = 0, 1, 2, and 3). Using the lactams as starting materials four synthetic routes were tested: salt elimination, transsilylation, transamination, and metallation of the lactames followed by reaction with methylchlorosilanes.
