The β-aminoimine [HC(CMe)2(NC6F5)2]H (1) is readily converted into the lithium β-diketiminate [HC(CMe)2(NC6F5)2]Li·OEt2 (2) by treatment with MeLi. The aluminum and gallium derivatives [HC(CMe)2(NC6F5)2}MMe2] (M = Al (3); Ga (4)) have been prepared via the CH4 elimination reactions of 1 with MMe3. The X-ray crystalstructures of 1 - 4 have been determined and the trends in metrical parameters are
通过用 MeLi 处理,β-氨基亚胺 [HC (CMe) 2 (NC6F5) 2] H (1) 很容易转化为 β-二酮亚胺酸锂 [HC (CMe) 2 (NC6F5) 2] Li · OEt2 (2)。铝和镓衍生物 [HC (CMe) 2 (NC6F5) 2} MMe2] (M = Al (3); Ga (4)) 是通过 1 与 MMe3 的 CH4 消除反应制备的。已经确定了 1-4 的 X 射线晶体结构,并讨论了度量参数的趋势。
