Abstract

Lithium TMP-aluminate “iBu3Al(TMP)Li” undergoes dismutation in THF solution to precipitate the tetraalkylaluminate [{Li·(THF)4}+{Al(iBu)4}–], but reacts kinetically as a TMP base towards N,N-diisopropylbenzamide to afford the crystalline ortho-aluminated species [(THF)3·Li{O(C)N(iPr)2(C6H4)}Al(iBu)3] and TMPH.
