A DFT (B3LYP/6-311++G(d,p) study of a series of N-H, N-methyl and N-propyl aziridines and their C-lithium derivatives has been carried out in order to explore their configurational as well as their NMR properties (1H and 13C). The results agree fairly well with experimental observations [Org Lett 9:1263, 2007 and J Org Chem 73, 2008 (73:3197)] and reveal the existence of lithium-N(lone pair) and lithium C(aromatic) interactions.

Abstract
A DFT (B3LYP/6-311++G(d,p) study of a series of N-H, N-methyl and N-propyl aziridines and their C-lithium derivatives has been carried out in order to explore their configurational as well as their NMR properties (1H and 13C). The results agree fairly well with experimental observations [Org Lett 9:1263, 2007 and J Org Chem 73, 2008 (73:3197)] and reveal the existence of lithium-N(lone pair) and lithium C(aromatic) interactions.File in questo prodotto:
