β ‐Diimine zinc dichloride complexes [CH 2 {C(Me)NAr} 2 ]ZnCl 2 [Ar = Mes ( 1 ), Dipp ( 2 )] were obtained from the reactions of ZnCl 2 with the corresponding β ‐iminoamines [ArN(H)C(Me)CHC(Me)NAr]. Complexes 1 and 2 were characterized by multinuclear NMR ( 1 H, 13 C) and IR spectroscopy, elemental analyses as well as by single‐crystal X‐ray diffraction. The energy differences between the enamine‐imine tautomers of the β ‐iminoamines were quantified by quantum chemical calculations.
