by treatment of the anilido-imine ligand o-C6H4N(C6H3iPr2-2,6)(CH = NC6H3iPr2-2,6) (L*) with H3Al·NMe3 in high yield. The formations of the two complexes both involve aluminum hydride addition to the C=N double bond. Compounds 1 and 2 were characterized by 1H NMR and IR spectroscopic, elementary analysis, and single-crystal X-ray diffraction studies.
o-C6H4F(CH = NC6H3iPr2-2,6) (L) 与 H3Al·NMe3 反应生成二氢化铝,配位 NMe3 的组成为 [o-C6H4F(CH2NC6H3iPr2-2,6)]AlH2(NMe3)(1)。此外,一氢化铝[o-C6H4N(C6H3iPr2-2,6)(CH2NC6H3iPr2-2,6)]AlH(NMe3)(2)是通过对苯胺基-亚胺配体o-C6H4N(C6H3iPr2-2,6 )(CH = NC6H3iPr2-2,6) (L*) 与 H3Al·NMe3 高产率。两种复合物的形成都涉及氢化铝加成到 C=N 双键。化合物 1 和 2 通过 1H NMR 和 IR 光谱、元素分析和单晶 X 射线衍射研究进行表征。
