摘要
In seeking to investigate whether structures of the type observed for {[Me3Al(TMP)]Li}(infinity). (TMP = 2,2,6,6-tetramethylpiperidide) can be oligomerised by the use of polyfunctional N-centred ligands, we report lithium aluminates incorporating RN -C(H)- NR residues. For PhN -C(Ph)- NPh =Am cluster cation-containing (Li4Am3)(+). {Li[(mu -Me)(2)Al(Me)Bu-t](2)](-) is afforded. However, the empolyment of PhN(H)(2-pyr) (pyr = pyridyl) instead affords both [Li-8(H)[N(2-pyr)Ph](6)}(+). [Li(Me2AlBu2t)(2)](-) and Li-7(H)[N(2-pyr)Ph](6): the first molecular Main Group clusters to incorporate interstitial hydride. Results indicate that R-elimination front (BuLi)-Li-t represents the source of H-. in these reactions.
