Abstract

Three Lewis base variations of the synthetically useful aluminate [L?Li(TMP)(iBu)Al(iBu)2], where L is TMPH, Et3N or PhC(LO)NiPr2, are reported, together with the reaction of the benzamide complex with 1,4-dioxane, which surprisingly leads to fragmentation of the cyclic ether and capture of its alkoxy vinyl ether residue within a novel dilithium dialuminium hexaalkyl aggregate.
