Herein we detail the synthesis and characterisation of a series of zirconium compounds featuring the bis(amido)silyl ligand [iPr2Si(NDipp)2]2− (Dipp = 2,6-diisopropylphenyl). The functionalisation of bis(amido)silyl zirconium halide complexes with a variety of nucleophiles, such as LiNMe2, LiBH4 and MeLi, was explored and the resulting products showed a propensity to form anionic zirconate salts when
本文中,我们详细介绍了一系列具有双(酰胺基)甲硅烷基配体[ i Pr 2 Si(NDipp)2 ] 2-(Dipp = 2,6-二异丙基苯基)的锆化合物的合成和表征。探索了双(酰胺基)甲硅烷基卤化锆配合物与多种亲核试剂如LiNMe 2,LiBH 4和MeLi的功能化,并且当在THF中进行合成时,所得产物显示出形成阴离子锆酸盐的倾向。锆酸盐产品之一[ i Pr 2 Si(NDipp)2 ] Zr(NMe 2)2 ·ClLi(THF)3具有在室温下在芳族溶剂中催化伯胺和仲胺硼烷的脱氢偶联的能力。

outcome is completely modified, thus leading selectively to the formation of high‐mass polybutylaminoborane. When extended to a variety of primaryamines, under solventless conditions and at low temperature, this reaction provides a new, efficient, and direct metal‐free access to high‐molecular‐mass polyaminoboranes in good to high yields under mild reaction conditions.
在室温下,二异丙基氨基硼烷与正丁胺的无溶剂反应会生成含B (sp2) H-,B (sp3) H 2-和B (sp3) H 3的混合物。在低温下,反应结果被完全改变,从而选择性地导致形成高质量的聚丁基氨基硼烷。当在无溶剂条件下和低温下扩展到多种伯胺时,该反应可在温和的反应条件下以高到高收率提供一种新的,有效的,无金属的高分子量聚氨基硼烷直接接触途径。
