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

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