The Manifold Structural Chemistry of Alkali Metal Enediamide Complexes

New alkali metal (M = Li, Na, K) enediamide complexes derived from 1,4‐diaza‐1,3‐dienes (= DADs) have been synthesized and structurally characterized. The complexes were prepared by direct metalation of either 1,4‐bis(2,6‐diisopropylphenyl)‐1,4‐diaza‐1,3‐butadiene (1, = H2DADDipp) or 1,4‐bis(2,6‐diisopropylphenyl)‐2,3‐dimethyl‐1,4‐diaza‐1,3‐butadiene (2, = Me2DADDipp) with an excess of the respective alkali metals in donor solvents such as THF or DME. All new complexes were fully characterized by spectroscopic methods and X‐ray crystallography. A series of new alkali metal (M = Li, Na, K) enediamide complexes derived from bulky 1,4‐diaza‐1,3‐dienes have been synthesized and structurally characterized. Trends in the structural chemistry of these useful compounds are discussed.
