A theoretical (HF/6-31G∗∗ and DFT, B3LYP/6-31G∗∗) study of the interactions between methyllithium and the DNA bases or several nucleosides is presented. Both the complexes following the binding of MeLi on these substrates and the structure of the entities resulting from the subsequent deprotonation reaction have been characterized.
