No N 2 Li 2 units are formed on dilithiation of the RNH‐substituted ethers 1 and 2 . Instead, the dimerization of two monomers leads to adamantanoid structures with Li 4 O 2 N 4 frameworks and CH 2 CH 2 OMe and CH 2 CH 2 NMe 2 side arms that are crucial for dimer formation. The adamantanoid structure of the Li 2 compound prepared from 1 also persists in solution.
