Abstract
The formation of mixed aggregates of N, N′-dilithiodiamines with alkyllithiums and lithium enolates was investigated. Enolization of 3-pentanone with the dilithium salt of N, N′-dimethyl-1,3-propanediamine generated both the E and Z enolates and the E/ Z ratio changed in the presence of a lithium enolate or excess butyllithium. The formation of mixed aggregates was modeled with the B3LYP DFT method and it was found that mixed aggregate formation is energetically favorable. The infrared spectra of dilithio- N, N′-dimethyl-1,3-propanediamine in the presence of excess butyllithium or lithium enolate are consistent with the formation of mixed aggregates.
