The stability of dimeric species in diluted solutions as well as reasons of their disaggregation in some cases has been discussed. For the lithioderivatives of 1,8-bis(dimethylamino)naphthalene (DMAN) the possibility of NMe2 group coordination to the lithium atom in ortho-position of naphthalene core under steric pressure of substituents was demonstrated by quantum chemical calculations. For the first time, dilithionaphthalenes were studied by 1H, 13C, and 7Li NMR spectroscopy. It was shown that while β-dilithionaphthalenes form oligomeric aggregates in solutions, α-dilithionaphthalenes exist as solely monomeric species with each lithium atom coordinated to both peri-positions.",
