the relative stoichiometry of the building block bis(trimethylsilyl)–N,N′–2,6–diaminopyridine (bap) and EtAlCl2 or AlCl3, different molecular entities (mononuclear and dinuclear complexes, pyridinophane and molecular bowl) containing aluminum centres have been synthesized. Efforts to extend the approach to synthesize triazinophanes with bis(trimethylsilyl)-N,N′-2,4-diamino‒6‒(R)‒triazines (R = Me, NH(SiMe3)
通过改变结构单元双(三甲基甲硅烷基)-N,N'-2,6-二氨基吡啶(间隙)和EtAlCl 2或AlCl 3的相对化学计量,可以得到含铝的不同分子实体(单核和双核配合物,吡啶并烷和分子碗)中心已综合。努力扩展在与AlMe反应中用双(三甲基甲硅烷基)-N,N'-2,4-二氨基‒6‒(R)‒三嗪(R = Me,NH(SiMe 3),Ph)合成三嗪并的方法图3显示了比类似吡啶基吡啶样结构更倾向于形成双核铝络合物。使用多核NMR,HRMS和单晶X射线衍射已对所有新化合物进行了全面表征。
