Abstract

Reaction of 1,8-C10H6NHSiMe32 (1) with 2 molar equiv of butyllithium in toluene and subsequently added hmpa or tmeda as neutral coligands yields the lithium compounds 1,8-C10H6{N(Li-hmpa)SiMe3}2 (2) or 1,8C10H6{N(Li)SiMe3}2(tmeda)1.52 (3), respectively which were both characterized by X-ray crystallography. Both compounds were obtained irrespective of the amide/coligand ratio in solution. Compound 3 is a dimeric complex containing two chelating and one bridging tmeda ligand. Lithiation of 1 in thf and reaction of the lithium amide with MgBr2(Et2O) gave the mixed-metal Li-Mg-amide 1,8-C10H6{NSiMe3}2Li(thf)MgBr(thf) (4). A singlecrystal X-ray structure analysis revealed that in the solid the MgBr units coordinate to neighboring lithium centers, leading to the aggregation of the molecules as polymeric chains.
