N,N'-Dimethyl-N,N'-diphenylethylenediamine

A. Lennartson, T. Kokoli and M. Håkansson

Abstract: The centrosymmetric title compound, C₁₆H₂₀N₂, was synthesized by deprotonation of N,N'-diphenylethylenediamine with n-BuLi in tetrahydrofuran. The coordination geometry around the N atoms is trigonal planar and the conformation about the ethane bond is staggered. The crystal structure displays intermolecular C-H interactions which give rise to infinite pleated layers extended in the bc plane. The possibility of obtaining an amine that can undergo crystallization-induced asymmetric transformation is discussed. This would enable the preparation of the pure enantiomers by absolute asymmetric synthesis.
