Aminolysis of Lithium/Yttrium Bimetallic Alkyls including the Solid‐State Structure of a Europium(II) <i>n</i>‐Butyl Compound

Abstract Using previously established salt‐metathesis procedures at low temperature, heterobimetallic ate complexes Li 6 Eu II ( n ‐Bu) 8 (thf) and 3 Y III i 4 could be synthesized their solid‐state structures analyzed by X‐ray diffraction. Recently described complex Y( was probed as a precursor in protonolyses with various amines, revealing distinct reaction pathways. Identified products comprise homoleptic amide Y[HNC H (mes) 2 ‐2,6] (mes=C Me ‐2,4,6), heteroleptic C−H‐bond activated [N(SiMe CH )(C ‐Me ‐3,5)] 5 , mixed amido/imido [LiY (HNSiPh ) (NSiPh ][Li(thf) (OEt ].
