N2 - 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, is the first example of a structurally characterized lithium enolate and contains Li centres that are intramolecularly coordinated.
