Attempted crystallization of the bis(aryl)lithium cuprate, Cu2Li2(C6H4CH2-NMe2-2)4, from diethyl ether/pentane afforded in according to an X-ray diffraction analysis appeared to be the lithium enolate, Li4[OC(=CH2)C6H4CH2NMe2-2]4. This consists of a central Li4O4 cube with intramolecular LiN coordination of the CH2NMe2 substituent. This enolate, which has also been prepared via an independent route
尝试根据X射线衍射分析从提供的乙醚/戊烷中结晶出双(芳基)锂铜酸铜Cu 2 Li 2(C 6 H 4 CH 2 -NMe 2 -2)4。烯醇盐Li 4 [OC(= CH 2)C 6 H 4 CH 2 NMe 2 -2] 4。它由具有分子内Li 4N配位的CH 2 NMe 2的中心Li 4 O 4立方体组成取代基。该烯醇化物也已经通过独立的途径制备,是结构特征化的烯醇锂的第一个实例,并且包含分子内配位的Li中心。
