Metallocene Coordination to Neutral Alkaline Earth Metal Complexes

Type: article

Abstract: The geometrically constrained, Lewis acidic magnesium diamide complex, [Mg( Et NON TCHP )] ( Et NON TCHP = 4,5‐bis(2,4,6‐tricyclohexylanilido)‐2,7‐diethyl‐9,9‐dimethyl‐xanthene), forms complexes with a series of metallocenes, [Mg( Et NON TCHP )(η 2 ‐Cp 2 M)] (M = Mn, Fe, Co, or Ni), in which one cyclopentadienyl ring of the metallocene is η 2 ‐coordinated to the magnesium center. Treating the heavier group 2 metal amide complexes, [M( Et NON TCHP ){N(H)(SiMe 3 ) 2 }] (M = Ca, Sr or Ba) with ferrocene yields complexes [M( Et NON TCHP )(η 5 ‐Cp 2 Fe)] in which one cyclopentadienyl ring of ferrocene is η 5 ‐coordinated to the group 2 metal center. Computational studies on the metallocene complexes reveal that the metallocene‐group 2 metal interactions are largely electrostatic in nature.
