Abstract
Crystals of a monomeric lithium dialkylaluminium amide containing two different chiral amide moieties have been isolated from the reaction of lithiated Schöllkopf’s bis‐lactim ether complexed by pmdta with the diethylaluminium amide of (S)‐α‐(methylbenzyl)benzylamine, with single crystal X‐ray diffraction revealing a migration of the Li cation in the aluminate from its initial position on the pyrazine ring of the lactim ether precursor.
