Description

含 β-Η的仲胺基金属有机化合物及其制备和应用 技术领域
本发明涉及含 β-Η的胺基金属有机化合物,属于材料制备技术领域,具体涉及含 β-Η 的仲胺基金属有机化合物材料, 其制备方法和应用。
背景技术
近年来, 金属有机化学的发展打破了传统有机化学和无机化学的界限, 同时又与理 论化学、 合成化学、 催化化学、 结构化学、 生物无机化学、 高分子科学、 材料科学等交 织在一起, 成为近代化学的前沿领域之一。 [Crabtree, Robert H. The organometaUic chemistry of the transition metals, John Wiley & Sons, 2009.]
胺基金属有机化合物作为有机金属化学的一个分支, 自 1856年 Frankland用二乙 基锌和仲胺经烷烃的消除反应得到第一个胺基金属化合物 Zn(NEt2)2以来, 成为研究热 点之一。
胺基金属化合物的研究对于化学键形成过程及特点的认识, 引入官能团方法的开 发, 以及其在烯烃聚合催化、 不对称合成、 模拟和了解生物酶体作用机理等各个领域, 都显示出了它的重要性, 受到广大化学工作者的青睐。
胺基(非)金属有机化合物通常指含有键合于 (非)金属 (M) 的一个或多个氮配 体(NH2,NHR和 NRR)的化合物,在配体的取代基中 R或 R'可以是相同或不同的, 如: 氢、 烷基 (alkyl)、 烯基 (alkenyl)、 炔基 (alkynyl)、 芳香基 (aryl)和硅基 (silyl)。 其结 构通式如示意式 1所示。
Figure imgf000002_0001
示意式 1 胺基金属有机化合物的结构示意图
胺基金属有机化合物主要有亚胺类 [D. E. Wigley, Prog. Inorg. Chem. , 1994, 42, 239-482.]、 胺类 [M. F. Lappert, P. P. Power, A. V. Protchenko, A. L. Seeber, Metal amide chemistry, Chichester, U.K.: Wiley, 2009]、 氮杂烯丙基类 [G. Witting, H. eiffm, Angew. Chem. , 1968, 80. 8.]、 脒类 [J. Barker, M. Kilner, Coord. Chem. Rev. , 1994, 133, 219-300.]和 β-二亚胺类等金属化合物 [L. Bourget-Merle, M. F. Lappert, K. . Severn, Chem. Rev., 2002, 102, 3031-3066. 式 2)。
Figure imgf000002_0002
示意式 2 胺基金属有机化合物的常见类型 胺基金属有机化合物的制备方法有多种, 包括: 烷烃消除法、 卤化铵消除法、 氢分 子消除法和氨分子置换法等。 (如下: Eq 1-5, L代表各种配体, M'=Li, Na)。
ZnEt2 + 2HN 2→ Zn(NR2)2 +2C2H6 1
LnMCl + 2HN 2→ LnMN 2 + [ 2NH2]C1 2
LnMX + M'NRR'→ MN ' +M'X 3
LnMH + HN '2→ LnMN '2 + ¾ 4
LnMN 2 + HN '2→ LnMNR'2 + HN 2 5
其中最常用的方法是式 2所示的氯化铵消除反应。 从 20世纪 60年代起有 Bradley和 Thomas提出的金属卤化物与胺基锂 (钠) 的交换反应 (式 3 ) 则是合成过渡金属胺基化 合物的主要方法。
胺基配体化合物是最广泛的配体化合物之一,胺基一般以伯胺、仲胺和叔胺的形式 存在, 相应的 MN¾, MNHR, MNRR'就是胺基金属化合物的存在形式。 MN¾通常可以 看作无机金属化合物, MNRR'是研究较多的金属胺基化合物, 而 MNHR鲜有报道。胺基 金属有机化合物的化学性质与等电子的烷基、 烷氧基金属化合物接近, 而不同于等电子 的氟金属化合物。 金属离子与配体成键的极性强弱次序为: M-R < M-NRR' < M-OR < M-F。
胺基金属化合物因具有碱性、还原性等特点, 广泛应用于有机合成、催化反应、 还 原反应等。 同时, 仲胺基金属化合物 MNHR分子内含有一定的氢量, 研究其直接脱氢和 吸氢性能有望实现其在储氢领域的应用。
氢由于资源丰富、 燃烧效率高、 无污染等, 被认为是理想的替代化石资源的二次能 源,现已成为全球研究的重点方向。 [Schlapbach L, Zuttel A. Hydrogen-storage materials for mobile applications. Nature, 2001, 414: 353-358.] 然而, 氢是所有元素中最轻的, 在常温 常压下为气态, 密度仅为 0.0899 kg/m3, 是水的万分之一, 因此高密度储存一直是一个 世界级难题。 目前, 安全、 高效、 经济的氢气储存技术已成为氢能实现实用化规模化应 用的瓶颈之一。
因此, 发展原料易得、操作简便、普适性强的制备方法合成胺基金属有机化合物并 研究其作为储氢材料的潜在可能具有重要意义。
