The solution structures of [bis(diethylamino)phenylsilyl]lithium (1), [(diethylamino)diphenylsilyl]lithium (2), and [(diethylamino)phenylmethylsilyl]lithium (3) were investigated by 13C, 29Si, 7Li, and 15N NMRspectroscopic experiments. The 29Si−7(6)Li coupling can be observed in each species at low temperature. The coupling patterns indicate that these three species exist as monomers in THF. Using
