| - Reaction of 1,8-C10H6{NHSiMe3}2 (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] or [1,8-C10H6{N(Li)SiMe3}2(tmeda)1.5]2. 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) for which a single-crystal 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.

Bothcompounds were obtained irrespective of the amide/coligand ratio in solution. Compound 3 is a dimeric complexcontaining two chelating and one bridging tmeda ligand. Lithiation of 1 in thf and reaction of the lithium amidewith MgBr2(Et2O) gave the mixed-metal Li−Mg−amide [1,8-C10H6{NSiMe3}2Li(thf)MgBr(thf)] (4).
