The oligomeric sodiumamides 1–3 , which were formed during attempts to metalate hydrocarbons with n ‐butylsodium in the presence of teteramethylethylenediamine, have stacked ring structures. Correspondingly structured lithium amides are not known; rather, in this case ladder structures should be preferred.
