Abstract:
The structure of 1-lithio-2-methoxybenzene in the presence of N,N,N',N'-tetramethylethylenediamine (TMEDA) has been detd. by single crystal x-ray diffraction techniques. The structure consists of two centrosym. related tetrameric units of lithiomethoxybenzene connected to each other by a bridging TMEDA ligand which has a center of inversion in the middle of the C-C bond. The nature of the highly asym. tetrameric unit is discussed and compared to that of other organolithium compds. with intramol. coordination through an ether function.
