A seven-membered N,N'-heterocyclic potassium alumanyl nucleophile is introduced and utilised in the metathetical synthesis of Mg-Al and Ca-Al bonded derivatives. Both species have been characterised by experimental and theoretical means, allowing a rationalisation of the greater reactivity of the heavier group 2 species implied by an initial assay of their reactivity.
Al‐Ca‐Wrap: Die Reaktion eines siebengliedrigen cyclischen Alumanyl‐Anions mit einem β‐Diketiminato‐Calciumtetraphenylborat bietet einen leichten Zugang zu einem stabilen, aber hochreaktiven Calcium‐Alumanyl.
Keywords: Alumanyl; Calcium; Dichtefunktionaltheorie; Kalium; Magnesium.
